Electronic signature of the vacancy ordering in NbO (Nb3O3)
A. K. Efimenko, N. Hollmann, K. Hoefer +15
We investigated the electronic structure of the vacancy-ordered 4d-transition metal monoxide NbO (Nb3O3) using angle-integrated soft- and hard-x-ray photoelectron spectroscopy as w…
Quantitative study of the f occupation in CeMIn5 and other cerium compounds with hard x-rays
M. Sundermann, F. Strigari, T. Willers +19
We present bulk-sensitive hard x-ray photoelectron spectroscopy (HAXPES) data of the Ce3d core levels and lifetime-reduced L edge x-ray absorption spectroscopy (XAS) in the partial…
Electronic and Spin States of SrRuO3 Thin Films: an X-ray Magnetic Circular Dichroism Study
S. Agrestini, Z. Hu, C. -Y. Kuo +14
We report a study of the local magnetism in thin films of SrRuO3 grown on (111) and (001) oriented SrTiO3 substrates using x-ray magnetic circular dichroism spectroscopy (XMCD) at…
State of Co and Mn in half-metallic ferromagnet CoMnSi explored by magnetic circular dichroism in hard X-ray photoelectron emission and soft X-ray absorption spectroscopies
Gerhard H. Fecher, Daniel Ebke, Siham Ouardi +8
The half-metallic Heusler compound CoMnSi is a very attractive material for spintronic devices because it exhibits very high tunnelling magnetoresistance ratios. This work repo…
Spectroscopic evidence for giant orbital moment and magnetic anisotropy induced by local distortions in alpha-CoV2O6
N. Hollmann, S. Agrestini, Z. Hu +9
We present a combined experimental and theoretical study on the local magnetism of the Co ions in the spin-chain compound CoV2O6, which crystallizes in two different allotropic pha…
Correlation effects in CaCu3Ru4O12
N. Hollmann, Z. Hu, A. Maignan +7
We have investigated the electronic structure of CaCu3Ru4O12 and LaCu3Ru4O12 using soft x-ray photoelectron and absorption spectroscopy together with band structure and cluster con…
