Strongly correlated electron systems present collective phenomena that demand the application of advanced experimental techniques for their understanding, many of them available only in large multi-user laboratories. The training of researchers and research groups capable of using such techniques at a high level is therefore essential. In this regular project, mobility resources are reque…
Remarkable collective effects in Condensed Matter Physics, such as superconductivity and colossal magnetoresistance, among others, occur in transition-metal oxides, where there is frequently a coupling of electronic degrees of freedom (spin, orbital and charge) between themselves and with the crystal lattice. In these cases, not only the electronic and structural ground states, but also t…
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 o…

This work consists in studying different compounds using the complementarity of the techniques of resonant magnetic x-ray diffraction, elastic and inelastic neutron scattering, and Raman spectroscopy. From the neutron scattering measurements, we intend to determine the magnetic structure as well as the nature of the transitions that the intermetallic compounds DyNiSi3 and HoNiSi3 present…
Compounds based on Ti3+ are of contemporary interest of the Condensed Matter Physics, because these ions have only a electron in the 3d shell, thus presenting an active orbital degree of freedom that may lead to non-trivial electronic ground states. This project consists on the synthesis and investigation of the ternary componds LaTiO3+d with different oxygen concentrations (0<=d<=0.5). T…
Electron correlation and spin-orbit coupling are ingredients that may endow materials with attractive properties. In this project, we will study variations of a particularly interesting material of this class: Sr2IrO4. Although this family is known to present a fermiology that is similar to cuprates, superconductivity under charge doping has not been observed so far, suggesting the existe…
In this project, resonant magnetic x-ray diffraction experiments on single crystals of the RNiSi3 series (R: Gd, Tb, Dy, Ho) will be performed and analyzed, using the XDS beamline of LNLS, aiming at determining their magnetic structures and nature of their phase transitions. A recent study of this family through magnetic susceptibility, resistivity and specific heat measurements indicates…

d-electron systems are an attractive field of study due to their rich variety of emergent phenomena, such as in high-temperature superconductivity (high-Tc), Mott insulators, and multiferroicity, which generally arise from strong electron correlation. One such example is the high-Tc cuprate family La2-xBaxCuO4. For x = 0, the Coulomb repulsion is so strong that these compounds are antifer…
