• 2015 IUCr High-Pressure Workshop, AO.R

• Abstract

  This projects fits well in the strategy to develop state-of-the-art experimental stations in the current synchrotron light source and which can be moved, without any modification, to the new synchrotron light source under construction. In particular, the possibility of studying any material (magnetic, superconducting, geological, biological, among others) under extreme pressure, temperatu…

  Multi-user equipment approved in grant 2013/22436-5: facility for high pressure experiments, AP.EMU

• Abstract

  The project here described here aims to nucleate a research group in synchrotron experiments at high pressures, temperature and magnetic field, unique in Brazil, which potentially can become an international reference in the study of materials under extreme conditions. This projects fits well in the strategy to develop state-of-the-art experimental stations in the current synchrotron ligh…

  Synchrotron Radiation techniques under extreme conditions, AP.JP

• Abstract

  Understand the behavior of an interacting or correlated electrons system in metallic compounds remains one of the major challenges in modern physics. A concept that has attracted considerable attention by the scientific community is the quantum criticality, which can occur by reducing the temperature characteristic of a second-order phase transition through the absolute zero using some ex…

  Unconventional phases of actinide compounds under extreme conditions, BP.PD

• Abstract

  In this project we propose to study the competition between magnetism and superconductivity and its dependence on electron density and correlation in high electron density systems and as a function of external pressure applied to induce high atomic and electron density. In order to do this, we will explore two classes of materials: heavy fermion intermetallics, which exhibit unconventiona…

  Magnetism and superconductivity under extreme conditions by x-ray techniques, BP.DR

• Abstract

  This research project aims to study intermetallic compounds with double perovskite structure using synchrotron radiation techniques under high pressures. Our goals are focused on the understanding the structural, electronic and magnetic properties as a function of physical pressure in materials that exhibit strong spin orbit coupling. The evolution of orbital and spin magnetic moment as a…

  ORBITAL MAGNETISM IN DOUBLE PEROVSKITE COMPOUNDS UNDER EXTREME CONDITIONS BY SYNCHROTRON RADIATION TECHNIQUES, BP.PD

(Only some records are available in English at this moment)

• Abstract

  We propose to study the electronic and magnetic properties of "Iridates" (Iridium containing oxides) where sizable spin-orbit interactions in third-row transition metal Ir ions lead to novel properties not achievable in oxides with first- and second-row transition metal ions. Double perovskite Sr2FeIrO6 displays competition between ferromagnetic and antiferromagnetic interactions, and the…

  Orbital magnetism in double perovskite compounds under extreme conditions by synchrotron radiation techniques, BE.EP.PD

• Abstract

  With this research project we propose to study the electronic, magnetic and atomic structure properties of bulk and thin films systems which exhibit the interplay between superconductivity and magnetism by performing advanced X-rays spectroscopy and X-ray diffraction techniques from synchrotron light sources. The ternary RERh4B4 compounds, with RE = Dy, Ho, Er and Tm, characterized by a c…
