Evidence for a temperature-induced spin-state transition of Co3+ in La2-xSrxCoO4
N. Hollmann, M. W. Haverkort, M. Benomar +3
We study the magnetic susceptibility of mixed-valent La2-xSrxCoO4 single crystals in the doping range of 0.5<= x <= 0.8 for temperatures up to 1000 K. The magnetism below room temp…
Magnetic correlations in La2-xSrxCoO4 studied by neutron scattering : possible evidence for stripe phases
M. Cwik, M. Benomar, T. Finger +4
Spin correlations in LSCO have been studied by neutron scattering. The commensurate antiferromagnetic order of the parent compound persists on a very short range up to a Sr content…
Anisotropic Susceptibility of La_2-xSr_xCoO_4 related to the Spin States of Cobalt
N. Hollmann, M. W. Haverkort, M. Cwik +4
We present a study of the magnetic susceptibility of La_2-xSr_xCoO_4 single crystals in a doping range 0.3<=x<=0.8. Our data shows a pronounced magnetic anisotropy for all compound…
Magnetoelastic coupling in RETiO3 (RE = La, Nd, Sm, Gd, Y)
A. C. Komarek, H. Roth, M. Cwik +6
A detailed analysis of the crystal structure in RETiO3 with RE = La, Nd, Sm, Gd, and Y reveals an intrinsic coupling between orbital degrees of freedom and the lattice which cannot…
Orbital excitations in titanates
C. Ulrich, A. Gössling, M. Grüninger +6
Raman scattering is used to observe pronounced electronic excitations around 230 meV - well above the two-phonon range - in the Mott insulators LaTiO and YTiO. Based on the…
Determination of the orbital moment and crystal field splitting in LaTiO
M. W. Haverkort, Z. Hu, A. Tanaka +18
Utilizing a sum-rule in a spin-resolved photoelectron spectroscopic experiment with circularly polarized light, we show that the orbital moment in LaTiO is strongly reduced bot…
