We are proposing the study of the electronic, structural, magnetic, transport and thermodynamic properties of highly correlated systems in extreme conditions of magnetic fields (?14 T), high pressures (?30 kbars) and low temperatures (?50 mK) in metallic, semi-metallic semiconductor materials, diluted magnetic semiconductors, multiferroic ceramic oxides, graphites, etc., involving fundamentally the electron-electron interactions and between conduction electrons with the transition elements of the 3d groups of Iron and 4f of Rare Earths. For this purpose experiments of resistivity, Hall effect, magnetization, dc/ac magnetic susceptibility, specific heat, magneto impedance, torquemetry, electronic paramagnetic resonance (EPR), Raman scattering, powder diffraction, magnetic action, and absorption of x-rays (XANES, EXAFS, XMCD) in samples in poly and monocrystalline form, thin films, threads, particles, nanostructured and amorphous multilayers will be conducted and analyzed during the course of this project.
