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…

Static and fluctuating stripe order observed by resonant soft x-ray diffraction in La1.8Sr0.2NiO4

J. Schlappa, C. F. Chang, E. Schierle +11

We studied the stripe phase of La1.8Sr0.2NiO4 using neutron diffraction, resonant soft x-ray diffraction (RSXD) at the Ni L2,3 edges, and resonant x-ray diffraction (RXD) at the Ni…

Spin blockade, orbital occupation and charge ordering in La_(1.5)Sr_(0.5)CoO4

C. F. Chang, Z. Hu, Hua Wu +9

Using Co-L_(2,3) and O-K x-ray absorption spectroscopy, we reveal that the charge ordering in La_(1.5)Sr_(0.5)CoO4 involves high spin (S=3/2) Co^2+ and low spin (S=0) Co^3+ ions. T…

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…

Anomalous expansion and phonon damping due to the Co spin-state transition in RCoO_3 with R = La, Pr, Nd and Eu

K. Berggold, M. Kriener, P. Becker +4

We present a combined study of the thermal expansion and the thermal conductivity of the perovskite series RCoO_3 with R = La, Nd, Pr and Eu. The well-known spin-state transition i…

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…
