Abstract
In this project we propose to intensify even more the study of the electronic, structural, magnetic, transport and thermodynamics properties of highly correlated materials under the extreme condition of high magnetic fields (d 14 T), low temperatures (e 50 mK) and high pressures (d 30 kbars) in metals, superconductors, semiconductors, semimetals, diluted magnetic semiconductors, ceramic oxides, multiferroics, graphite, graphene, etc., involving, mainly, the interactions between conduction-electrons and between conduction-electrons and the transition elements of the 3d Iron and 4f Rare-Earths groups. For these purpose we plan to perform during this project the following experiments: resistivity, Hall effect, magnetization, magnetic susceptibility ac/dc, specific heat, magnetoimpidance, torquimetry, electron spin resonance (ESR), nuclear magnetic and quadrupolar resonance (NMR and NQR), Raman scattering, X-ray powder/magnetic diffraction/absorption (XANES, EXAFS, XMCD) and infrared absorption for poli crystals, single crystals, amophous, thin films and nanostructured multilayers, wires and particles samples. In order to shed new light on our current understanding of the phenomena involved in our research within the present Project, we also intend to incorporate the following techniques to our group: NMR/NQR, EDX, WDS, FT-IR and an IR Image Furnace which are necessary and crucial for the analysis and preparation of the new and complex materials which will be synthesized during this project.
