Konings, S., Schuessler-Langeheine, C., Ott, H., Weschke, E., Schierle, E., Goedkoop, J. B.
We report the direct observation of slow fluctuations of helical antiferromagnetic domains in an ultra-thin holmium film using coherent resonant magnetic x-ray scattering. We observe a gradual...
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...
X-Ray Scattering at Lanthanide M5 Resonances: Application to Magnetic Depth Profiling (2005)
Ott, H., Schuessler-Langeheine, C., Schierle, E., Grigoriev, A. Yu., Leiner, V., Zabel, H., ...
Quantitative analyses of x-ray scattering from thin films of Ho and Dy metal at the M_5 resonances result in values of the optical constants and the magnetic scattering lengths f_m, with f_m as large...
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...
Determination of the orbital moment and crystal field splitting in LaTiO$_{3}$ (2004)
Haverkort, M. W., Hu, Z., Tanaka, A., Ghiringhelli, G., Roth, H., Cwik, M., ...
Utilizing a sum-rule in a spin-resolved photoelectron spectroscopic experiment with circularly polarized light, we show that the orbital moment in LaTiO$_3$ is strongly reduced both below and above...
