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…
Investigation of element-specific and bulk magnetism, electronic and crystal structures of La{0.70}Ca{0.30}Mn{1-x}Cr{x}O{3}
H. Terashita, J. C. Cezar, F. M. Ardito +2
The magnetic interactions in La{0.70}Ca{0.30}Mn{1-x}Cr{x}O{3} (x = 0.15, 0.50 and 0.70) are investigated by x-ray absorption spectroscopy (XAS), x-ray magnetic circular dichroism (…
Pressure and chemical substitution effects in the local atomic structure of BaFe2As2
E. Granado, L. Mendonca-Ferreira, F. Garcia +10
The effects of K and Co substitutions and quasi-hydrostatic applied pressure (P<9 GPa) in the local atomic structure of BaFe2As2, Ba(Fe{0.937}Co{0.063})2As2 and Ba{0.85}K{0.15}Fe2A…
Unconventional Landau levels in bulk graphite revealed by Raman spectroscopy
A. F. Garcia-Flores, H. Terashita, E. Granado +1
The electronic Raman scattering of bulk graphite at zero magnetic field reveals a structureless signal characteristic of a metal. For T<~100 K and B > 2 T, several peaks at energie…
Doping Dependence of Polaron Hopping Energies in La(1-x)Ca(x)MnO(3) (0<= x<= 0.15)
K. P. Neupane, J. L. Cohn, H. Terashita +1
Measurements of the low-frequency (f<= 100 kHz) permittivity at T<= 160 K and dc resistivity (T<= 430 K) are reported for La(1-x)Ca(x)MnO(3) (0<= x<= 0.15). Static dielectric const…
A new method for analyzing second-order phase transitions applied to the ferromagnetic transition of a polaronic system
A. Souza, Yi-Kuo Yu, J. J. Neumeier +2
A new method for analyzing second-order phase transitions is presented and applied to the polaronic system LaCaMnO. It utilizes heat capacity and thermal expa…
