Resonant soft x-ray scattering from stepped surfaces of SrTiO3 (2008)
Schlappa, J., Schüßler-Langeheine, C., Chang, C. F., Hu, Z., Schierle, E., Ott, H., ...
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 data. The steps on...
Manipulating the magnetic structure by electric fields in multiferroic ErMn2O5 (2007)
Bodenthin, Y., Staub, U., Garcia-Fernandez, M., Janoschek, M., Schlappa, J., Golovenchits, E. I., ...
Based on measurements of soft x-ray magnetic diffraction under in-situ applied electric field, wereport on significantly manipulation and exciting of commensurate magnetic order in multiferroic...
Direct observation of t2g orbital ordering in magnetite (2006)
Schlappa, J., Schuessler-Langeheine, C., Chang, C. F., Ott, H., Tanaka, A., Hu, Z., ...
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. The spectra show...
Spectroscopy of stripe order in La1.8Sr0.2NiO4 using resonant soft x-ray diffraction (2005)
Schuessler-Langeheine, C., Schlappa, J., Tanaka, A., Hu, Z., Chang, C. F., Schierle, E., ...
Strong resonant enhancements of the charge-order and spin-order superstructure-diffraction intensities in La1.8Sr0.2NiO4 are observed when x-ray energies in the vicinity of the Ni L2,3 absorption...
