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…
Crystal-field level inversion in lightly Mn-doped Sr3Ru2O7
M. A. Hossain, Z. Hu, M. W. Haverkort +17
Sr3(Ru1-xMnx)2O7, in which 4d-Ru is substituted by the more localized 3d-Mn, is studied by x-ray dichroism and spin-resolved density functional theory. We find that Mn impurities d…
High multipole transitions in NIXS: valence and hybridization in 4f systems
R. A. Gordon, G. T. Seidler, T. T. Fister +4
Momentum-transfer (q) dependent non-resonant inelastic x-ray scattering measurements were made at the N4,5 edges for several rare earth compounds. With increasing q, giant dipole r…
Determining the crystal-field ground state in rare earth Heavy Fermion materials using soft-x-ray absorption spectroscopy
P. Hansmann, A. Severing, Z. Hu +10
We infer that soft-x-ray absorption spectroscopy is a versatile method for the determination of the crystal-field ground state symmetry of rare earth Heavy Fermion systems, complem…
Local electronic structure and magnetic properties of LaMn0.5Co0.5O3 studied by x-ray absorption and magnetic circular dichroism spectroscopy
T. Burnus, Z. Hu, H. H. Hsieh +8
We have studied the local electronic structure of LaMn0.5Co0.5O3 using soft-x-ray absorption spectroscopy at the Co-L_3,2 and Mn-L_3,2 edges. We found a high-spin Co^{2+}--Mn^{4+}…
Orbital-assisted metal-insulator transition in VO
M. W. Haverkort, Z. Hu, A. Tanaka +9
We found direct experimental evidence for an orbital switching in the V 3d states across the metal-insulator transition in VO. We have used soft-x-ray absorption spectroscopy…
