The charge-ordered state in a quasi-two-dimensional organic superconductor β''−(BEDT-TTF)4[(H3O)Ga(C2O4)3]⋅C6H5NO2 has been investigated using C13 NMR spectroscopy in a high magnetic field. Enhanced resolution of the high-field spectrum allows us to estima ...
In layered superconductors, Josephson junctions may be formed within the unit cell1,2,3 as a result of sufficiently low inter-layer coupling. These intrinsic Josephson junction (iJJ) systems4 have attracted considerable interest for their application poten ...
Vanadium sesquioxide V2O3 is considered a textbook example of Mott-Hubbard physics. In this paper, we present an extended optical study of its whole temperature/doping phase diagram as obtained by doping the pure material with M = Cr or Ti atoms (V1-x M-x) ...
This work is devoted to the study of spin S = 1 systems, and more precisely to the emergence of exotic quantum phases in such systems, and to the establishment of tools to observe such phases. It is split in four main chapters. In the first chapter, we sho ...
We investigate transport through ionic liquid gated field effect transistors (FETs) based on exfoliated crystals of semiconducting WS2. Upon electron accumulation, at surface densities close to, or just larger than, 10(14) cm(2), transport exhibits metalli ...
Using quantum Monte Carlo simulations along with higher-order spin-wave theory, bond-operator and strong-coupling expansions, we analyze the dynamical spin structure factor of the spin-half Heisenberg model on the square-lattice bilayer. We identify distin ...
High-temperature superconductivity emerges on doping holes or electrons into antiferromagnetic copper oxides. The large energy scale of magnetic excitations, for example, compared with phonon energies, is thought to drive superconductivity with high transi ...
The low-temperature microscopic magnetic properties of the quasi-2D heavy-fermion compound, CePt2In7 are investigated by using a positive muon-spin rotation and relaxation (mu+SR) technique. Clear evidence for the formation of a commensurate antiferromagne ...
This thesis works reports on the magnetic properties of single transition metal atoms and hydrogenated compounds adsorbed on crystal surfaces. It is an experimental study, based on scanning tunneling microscopy (STM), initiated by the project of demonstrat ...
The Kondo effect arises due to the interaction between a localized spin and the electrons of a surrounding host. Studies of individual magnetic impurities by scanning tunneling spectroscopy have renewed interest in Kondo physics; however, a quantitative co ...
