Abstract

Collective behavior of interacting electrons in solids usually leads to the emergence of several complex phenomena in condensed matter such as superconductivity, magnetoresistance, thermoelectricity, complex magnetic ordering, multiferroic properties, metal-insulator transitions, non-Fermi-Liquid behavior (NFL), manifestation of topologically protected edge and/or surface states, etc. All these phenomena are governed by non-trivial microscopic parameters that are very hard to determine experimental and/or to model theoretically. Therefore, in this Project, our goal is to investigate the evolution of these emergent phenome in system with reduced dimensionality, which included small size systems (nanoparticle, nanowires, etc.) and low dimensional (2 D, 1D) massive systems. In order to reach our goals, we will make use of our expertise in synthesis and both microscopic and macroscopic materials characterization techniques using the following experiments: resistivity, Hall effect, magnetization, magnetic susceptibility ac/dc, specific heat, magnetoimpedance, torquimetry, electron spin resonance (ESR), nuclear magnetic and quadrupolar resonance (NMR and NQR), Raman scattering, X-ray powder/magnetic diffraction/absorption (XANES, EXAFS, XMCD) Elemental analysis (EDS e WDS) and Angle Resolved Photoemission Spectroscopy (ARPES). The deep understanding of these complex phenomena in condensed matters is crucial to drive new scientific and technological developments to strategic areas of research in condensed matters, such as: new materials design, devices design and functionalization, nanoscience and medicine, energy efficiency, high field generation, quantum computing, optical devices, spintronics, etc. (AU)
