Characterization of two electronic subsystems in cuprates through optical conductivity

Ana Akrap, Edoardo Martino, Neven Barisic

Understanding the physical properties of unconventional superconductors as well as of other correlated materials presents a formidable challenge. Their unusual evolution with doping, frequency, and temperature has frequently led to non-Fermi-liquid (non-FL ...

One-dimensional composite host-guest structure in BaVS3

László Forró, Gervais Chapuis, Alla Arakcheeva, Helmuth Berger, Philip Pattison, Neven Barisic

A detailed synchrotron X-ray diffraction (XRD) study performed with a single crystal of BaVS3 (barium vanadium trisulfide) in the temperature range between 10 and 295 K is reported. Aside from the known tetragonal–orthorhombic (240 K) and orthorhombic–mono ...

Scattering-dominated high-temperature phase of 1T-TiSe2: An optical conductivity study

László Forró, Helmuth Berger, Eduard Tutis, Neven Barisic

The controversy regarding the precise nature of the high-temperature phase of 1T-TiSe2 lasts for decades. It has intensified in recent times when new evidence for the excitonic origin of the low-temperature charge-density wave state started to unveil. Here ...

Mechanical and electronic properties of vanadium oxide nanotubes

László Forró, Arnaud Magrez, Andras Kis, Jin Won Seo, Balazs Sipos, Martial Duchamp, Neven Barisic

Vanadium oxide nanotubes with a diameter of 20-100 nm and an aspect ratio of 50-100 were synthesized by hydrothermal method. Young's modulus of 20-80 GPa was obtained by bending measurements of individual nanotubes using an atomic force microscope. Electri ...

Transport and magnetic properties of BaVSe3

László Forró, Helmuth Berger, Ana Akrap, Vladan Stevanovic, Neven Barisic

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 resistivi ...

Matthiessen's rule in MgB2: Resistivity and T-c as a function of point defect concentration

László Forró, Richard Gaal, Balazs Sipos, Janusz Andrzej Karpinski, Neven Barisic

We present the results of a systematic study of the temperature-dependent resistivity and of T-c of a single crystal MgB2 sample as a function of point defect concentration. We have found linear, albeit weak, correlation between the decreasing superconduct ...

Study of novel electronic conductors : the case of BaVS3

Neven Barisic

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 ...
