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…
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…
Magnetic and structural transitions in LaCoO ( = Ca, Sr, and Ba)
M. Kriener, M. Braden, H. Kierspel +4
We report thermal-expansion, lattice-constant, and specific-heat data of the series La_1-xA_xCoO_3 for 0<= x <= 0.30 with A = Ca, Sr, and Ba. For the undoped compound LaCoO_3 the t…
Thermodynamic properties of the field-induced Neel order of TlCuCl3
S. Stark, O. Heyer, A. Vasiliev +3
TlCuCl3 shows a quantum phase transition from a spin-gap phase to a Neel-ordered ground state as a function of magnetic field around H_{C0}~4.8T. From measurements of the specific…
The spin state transition in LaCoO; revising a revision
M. W. Haverkort, Z. Hu, J. C. Cezar +11
Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co- edge we reveal that the spin state transition in LaCoO can be well described by a…
