Abstract

We report a comprehensive study of transport, magnetotransport, and magnetic properties of single crystals of BaVSe3. The paramagnetic metal-ferromagnetic metal transition at 43 K was followed as a function of pressure by measuring the electrical resistivity and the thermoelectric power. The exponent of the low-temperature power-law dependence of the resistivity increases with pressure. The effective magnetic moment obtained from magnetic susceptibility in the paramagnetic regime is mu(eff)=1.40 mu(B). The study was completed by band-structure calculations based on density-functional theory both at ambient and high pressures. Transport coefficients of BaVSe3 resemble the high-pressure phase of BaVS3, which suggest that the replacement of sulfur with selenium can be viewed as chemical pressure.

transition metal oxides are antiferromagnetic Mott insulators. Among them, low dimensional geometrically frustrated systems, such as

\mathrm{Cu_2OSO_4}

shows typical signatures for a canted-AFM ground state with a weak ferromagnetic component. On the other hand,

and

display totally different behavior: the former is a Mott insulator while the latter is metallic and becomes superconducting at low temperature. Here we report the synthesis of large single crystals of

This thesis presents the results of a concerted effort to understand the complex array of physical properties exhibited by the BaVS3 family of materials. As a 3d1 system, BaVS3 displays a unique collection of correlation-driven phenomena, including a metal-insulator transition driven by spin-density waves and or charge-density waves as well as a pressure-dependent crossover between the non-Fermi-liquid and Fermi-liquid behaviors. In an attempt to better understand these and many other properties, we have undertaken a systematic experimental study of BaVS3 and related compounds. The primary measurements carried out were those of the transport properties, resistivity and thermoelectric power (TEP). Through the construction of specialized measuring apparatuses, we were able to measure simultaneously these transport properties under conditions of variable temperature (from 2 to 600 K), pressure (up to 3 GPa) and magnetic field (up to 12 T). At ambient pressure and in the range of 250 to 600K, BaVS3 shows nearly isotropic but poor metallic behavior with linear temperature dependences of resistivity and TEP and a Curie-like magnetic susceptibility. The nearly isotropic conductivity contrasts with the 1D 2kF fluctuations observed by lowering the temperature below 250 K (at which the first Jahn-Teller structural phase transition occurs) deep in the metallic phase. The fluctuations reveal the 1D aspects of the electronic character, originating from the chain like structure of the material. The salient feature of BaVS3 at ambient pressure is the second order metal-to-insulator (MI) transition at TMI = 69 K, accompanied by the tetramerization (doubling of the 2V unit cell in the chain direction). In addition to the transport measurements, the strong changes in the electrical and magnetic properties of the system around TMI were followed by magnetic susceptibility, angle-resolved photoelectron spectroscopy and frequency-dependent conductivity. By increasing the pressure, the three-dimensionality of BaVS3 is enhanced and the MI phase transition is suppressed to lower temperatures. TEP and magneto TEP measurements in this pressure range revealed the existence of polarons and of spin fluctuations in the metallic phase. The latter can be identified as precursors to the MI transition. Around 1.8 GPa, where TMI ~15 K, the system enters a strongly fluctuating regime, highly sensitive to the magnetic field, the amplitude and the frequency of the measuring current and to a further increase of the pressure. Closely related to these features, the phase boundary collapses and a hysteretic behavior appears in the transport properties and their magnetic-field-dependent counterparts. At a critical pressure of ~2 GPa, a non-Fermi liquid (NFL) state arises (with n~1.5 in the Tn resistivity law between 1 and 15 K) in relation to the proximate Quantum Critical Point. The p-H-T phase diagram of BaVS3 in this region has been explored in some detail with particular emphasis placed upon the relevance of the spin degrees of freedom (on the insulator side) and the role of quantum fluctuations above the critical pressure. Finally, as the pressure is increased further, the conventional Fermi-liquid exponent of n = 2 is obtained. In order to delve further into the subtleties of the MI transition and the NFL behavior, a comparative study was carried out on the sister compounds Bax-1SrxVS3 and BaVS3 and on sulfur-deficient BaVS3. From this study it became apparent that the imposed chemical substitution manifests itself as an additional effective pressure. The inherent disorder of these samples was observed to affect the NFL behavior by reducing the exponent n towards a value of 1, while the apparent ferromagnetic order below 15 K was seemingly independent of pressure. All the observed features are consistent with a relatively simple two-band tight-binding, vanadium-based, model consisting of a wide quasi one-dimensional band hybridized with a rather isotropic narrow band. Within this context, it is concluded that the MI transition is controlled by the Coulomb-interacting electrons of the wide quasi one-dimensional band. Based on this model a new description of the NFL regime has been proposed.

The phenomenon of magnetism is one of the key components of today's technological progress. Magnetic interactions and magnetic materials are essential for the scientific disciplines of physics, chemistry and biology, making this subject truly multidisciplinary. This thesis is devoted to magnetic properties of two classes of substances. The first class represents the complexes of the ions of paramagnetic metals, primarily of the gadolinium(III) ion. These molecular compounds have an important application as magnetic resonance imaging (MRI) contrast agents for medical diagnostics. The design of more efficient MRI contrast agents requires a detailed knowledge of their magnetic properties. The other part of the thesis considers the broad class of recently discovered carbon nanostructures and materials. Their extraordinary physical properties foretell future applications of these materials in electronics, medicine and other fields. For instance, carbon nanotubes loaded with gadolinium(III) ion clusters are highly efficient MRI contrast agents. By using accurate density functional theory calculations in combination with classical molecular dynamics simulations, we determine hyperfine and quadrupole coupling constants on the nuclei of a first coordination sphere water molecule in gadolinium(III) aqua complexes. These parameters play a crucial role in the description of the key function, relaxivity, of MRI contrast agents. We found that the spin-polarization effect induced by the paramagnetic gadolinium(III) ion results in a Fermi contact hyperfine coupling of both the 1H and 17O nuclear spins and affects the dipole hyperfine coupling of the 17O nuclear spin of the inner coordination sphere water molecule. The 17O quadrupole coupling parameters of a coordinated water molecule are found to be very similar to that of neat water. We also apply the methodology of first principles molecular dynamics in order to perform realistic simulations of paramagnetic metal ions in water solution. This allows us to assess structure, dynamics and hyperfine interactions on the water molecules in the inner and outer coordination spheres of two metal ions: chromium(III) and gadolinium(III). In order to perform such calculations, we develop a novel approach for the evaluation of hyperfine coupling constants in pseudopotential electronic structure techniques. Our method takes into account the contribution of core electrons. In the second part of the thesis, we consider magnetic properties of a broad class of carbon nanostructures derived from two-dimensional graphene. We find that in metallic carbon nanotubes, an isotropic Knight shift, a hyperfine contribution to the nuclear magnetic resonance chemical shift, shows a regular dependence on the nanotube diameter. By using a more general approach, we reveal systematic dependences of magnetic interactions between arbitrarily distributed spin-polarized conduction electrons and nuclear spins in the carbon nanostructures derived from graphene. This knowledge is important for interpreting the results of magnetic resonance experiments and for evaluating the performance of carbon nanostructures as materials for alternative approaches in electronics, spintronics and quantum information processing based on electron and nuclear spins. In addition, we study magnetism in graphene induced by single-atom defects. The predicted itinerant magnetism due to the defect-induced states in graphenic materials may account for the experimental observations of ferromagnetism in irradiated graphite which has potential applications in technology. Finally, our first principles molecular dynamics study reveals the mechanisms of the irradiation-induced defect formation. We show that certain defect structures in layered carbon materials can be created selectively by irradiation at predefined conditions.
