Indication of a non-magnetic surface layer on a magnetic single crystal
Daniel Wegner, Gunter Kaindl
The structural and electronic properties of the surfaces of Sm(0001) and Eu/Gd(0001) were studied by scanning tunneling microscopy and spectroscopy at temperatures between 10 and 1…
Resonant soft x-ray scattering from stepped surfaces of SrTiO3
J. Schlappa, C. Schüßler-Langeheine, C. F. Chang +9
We studied the resonant diffraction signal from stepped surfaces of SrTiO3 at the Ti 2p -> 3d (L2,3) resonance in comparison with x-ray absorption (XAS) and specular reflectivity d…
Temperature-induced reversal of magnetic interlayer exchange coupling
K. M. Doebrich, M. Wietstruk, J. E. Prieto +4
For epitaxial trilayers of the magnetic rare-earth metals Gd and Tb, exchange coupled through a non-magnetic Y spacer layer, element-specific hysteresis loops were recorded by the…
Effects of impurities on Tamm-like lanthanide-metal surface states
D. Wegner, A. Bauer, G. Kaindl
The effects of isolated residual-gas adsorbates on the local electronic structure of the Dy(0001) surface were spatially mapped by scanning tunneling microscopy and spectroscopy at…
Direct observation of t2g orbital ordering in magnetite
J. Schlappa, C. Schuessler-Langeheine, C. F. Chang +8
Using soft-x-ray diffraction at the site-specific resonances in the Fe L23 edge, we find clear evidence for orbital and charge ordering in magnetite below the Verwey transition. Th…
Surface-electronic structure of La(0001) and Lu(0001)
D. Wegner, A. Bauer, Yu. M. Koroteev +4
Most spectroscopic methods for studying the electronic structure of metal surfaces have the disadvantage that either only occupied or only unoccupied states can be probed, and the…
