Anisotropic Lattice Compression and Pressure-Induced Electronic Phase Transitions in SrIrO
K. Samanta, R. Tartaglia, U. F. Kaneko +2
The crystal lattice of SrIrO is investigated with synchrotron X-ray powder diffraction under hydrostatic pressures up to GPa and temperatures down to K. The tet…
Magnetic structure and magnetoelastic coupling of GdNiSi3 and TbNiSi3
R. Tartaglia, F. R. Arantes, C. W. Galdino +4
The series of intermetallic compounds NiSi ( = rare earth) shows interesting magnetic properties evolving with and metamagnetic transitions under applied magnetic fie…
Tetragonal-orthorhombic phase coexistence under magnetic fields in BaFeAs and Sr(FeCo)As: evidence of magnetically driven structural transition
U. F. Kaneko, C. B. R. Jesus, M. E. Saleta +3
Synchrotron x-ray diffraction experiments were performed on BaFeAs and Sr(FeCo)As single crystals as a function of temperature and applied magnetic fi…
Nematic Fluctuations and Phase Transitions in LaFeAsO: a Raman Scattering Study
U. F. Kaneko, P. F. Gomes, A. F. Garcia-Flores +5
Raman scattering experiments on LaFeAsO with splitted antiferromagnetic (T_AFM = 140 K) and tetragonal-orthorhombic (T_S = 155 K) transitions show a quasi-elastic peak (QEP) in B2g…
Magnetic dimers and trimers in the disordered spin system BaTiMnO
F. A. Garcia, U. F. Kaneko, E. Granado +7
We report a structural/magnetic investigation by X-ray absorption spectroscopy (XAS), neutron diffraction, dc-susceptibility ($χ_{\mbox{dc}}$) and electron spin resonance (ESR) of…
Spin-Electron-Phonon Excitation in Re-based Half-Metallic Double Perovskites
A. F. Garcia-Flores, A. F. L. Moreira, U. F. Kaneko +6
A remarkable hardening (~ 30 cm-1) of the normal mode of vibration associated with the symmetric stretching of the oxygen octahedra for the Ba2FeReO6 and Sr2CrReO6 double perovskit…
