Transition probability functions for inelastic electron--electron scattering
Stefan Löffler, Peter Schattschneider
In this work, the transition matrix elements for inelastic electron--electron scattering are investigated. The angular part is given by spherical harmonics. For the weighted radial…
Electron vortices in crystals
Stefan Löffler, Peter Schattschneider
The propagation of electron beams carrying angular momentum in crystals is studied using a multislice approach for the model system Fe. It is found that the vortex beam is distorte…
Thermoelectric properties of Ba-Cu-Si clathrates
X. Yan, M. X. Chen, S. Laumann +4
Thermoelectric properties of the type-I clathrates BaCuSi (, = nominal Cu content) are investigated both experimentally and theoretically. T…
Field-induced Magnetic Transition in Cobalt-Ferrite
Martin Kriegisch, Weijun Ren, Reiko Sato-Turtelli +3
We present magnetostriction and magnetization measurements of a cobalt ferrite Co0.8Fe2.2O4 single crystal. We observe unusual behaviour in the magnetic hard axis of the single cry…
Calculation of coercivity of magnetic nanostructures at finite temperatures
D. Suess, L. Breth, J. Lee +7
We report a finite temperature micromagnetic method (FTM) that allows for the calculation of the coercive field of arbitrary shaped magnetic nanostructures at time scales of nanose…
Temperature-dependent multi-k magnetic structure in multiferroic Co3TeO6
S. A. Ivanov, R. Tellgren, C. Ritter +6
A complex magnetic order of the multiferroic compound Co3TeO6 has been revealed by neutron powder diffraction studies on ceramics and crushed single crystals. The compound adopts a…
