Electronic and magnetic properties of the kagome systems YBaCo4O7 and YBaCo3MO7 (M=Al, Fe)
N. Hollmann, Z. Hu, M. Valldor +6
We present a combined experimental and theoretical x-ray absorption spectroscopy (XAS) study of the new class of cobaltates YBaCo4O7 and YBaCo3MO7 (M= Al, Fe). The focus is on the…
Epitaxy, stoichiometry, and magnetic properties of Gd-doped EuO films on YSZ (001)
R. Sutarto, S. G. Altendorf, B. Coloru +12
We have succeeded in preparing high-quality Gd-doped single-crystalline EuO films. Using Eu-distillation-assisted molecular beam epitaxy and a systematic variation in the Gd and ox…
Epitaxial and layer-by-layer growth of EuO thin films on yttria-stabilized cubic zirconia (001) using MBE distillation
R. Sutarto, S. G. Altendorf, B. Coloru +11
We have succeeded in growing epitaxial and highly stoichiometric films of EuO on yttria-stabilized cubic zirconia (YSZ) (001). The use of the Eu-distillation process during the mol…
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…
Low energy excitations in CoO studied by temperature dependent x-ray absorption spectroscopy
M. W. Haverkort, A. Tanaka, Z. Hu +4
We have measured the intricate temperature dependence of the Co L2,3 x-ray absorption spectra (2p-3d excitations) of CoO. To allow for accurate total electron yield measurements, t…
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…
