Lattice dynamics of endotaxial silicide nanowires
J. Kalt, M. Sternik, B. Krause +17
Self-organized silicide nanowires are considered as main building blocks of future nanoelectronics and have been intensively investigated. In nanostructures, the lattice vibrationa…
Revealing charge anisotropies in metal compounds via high-purity x-ray polarimetry
Lena Scherthan, Juliusz A. Wolny, Isabelle Faus +12
Linear polarization analysis of hard x-rays is employed to probe electronic anisotropies in metal-containing complexes with very high selectivity. We use the pronounced linear dich…
Lattice dynamics and polarization-dependent phonon damping in -phase FeSi nanoislands
J. Kalt, M. Sternik, B. Krause +16
We determined the lattice dynamics of metastable, surface-stabilized -phase FeSi nanoislands epitaxially grown on the Si(111) surface with average heights and widths ranging…
Nuclear resonant scattering from 193Ir as a probe of the electronic and magnetic properties of iridates
Pavel Alexeev, Olaf Leupold, Ilya Sergueev +6
The high brilliance of the modern synchrotron radiation sources facilitates experiments with high energy x-rays. In this Letter we report on Nuclear Resonance Scattering at the 73…
A medium-resolution monochromator for 73 keV x-rays - Nuclear resonant scattering of synchrotron radiation from 193-Ir
Pavel Alexeev, Frank-Uwe Dill, Hans-Christian Wille +5
We report on the development and characterization of a medium resolution monochromator for synchrotron-based hyperfine spectroscopy at the 73 keV nuclear resonance of 193-Ir. The d…
Valence and magnetic instabilities in Sm compounds at high pressures
A. Barla, J. -P. Sanchez, J. Derr +8
We report on the study of the response to high pressures of the electronic and magnetic properties of several Sm-based compounds, which span at ambient pressure the whole range of…
