Effect of Coulomb interaction on the spin-galvanic mode in a two dimensional electron gas with Rashba spin-orbit interaction
Ya. B. Bazaliy, B. V. Bazaliy, G. Guntherodt +1
Recently a new propagating mode of coupled charge and spin oscillations was predicted in a two dimensional electron gas with a sufficiently strong Rashba interaction. We show that…
Asymmetric magnetization reversal in the exchange bias system Fe/FeF_2 studied by MOKE
A. Tillmanns, S. Oertker, B. Beschoten +3
The asymmetry of the magnetization reversal process in exchange biased Fe/FeF has been studied by magneto-optical Kerr effect. Qualitatively different transverse magnetization…
Role of structural defects on exchange bias in the epitaxial CoO/Co system
M. R . Ghadimi, B. Beschoten, G. Güntherodt
We have studied the influence of non-magnetic defects throughout the antiferromagnet Co_{1-y}O on the exchange bias (EB) in epitaxially grown Co_{1-y}O/Co bilayers. These defects a…
Magneto-optical study of magnetization reversal asymmetry in exchange bias
A. Tillmanns, S. Oertker, B. Beschoten +4
The asymmetric magnetization reversal in exchange biased Fe/MnF involves coherent (Stoner-Wohlfarth) magnetization rotation into an intermediate, stable state perpendicular t…
Energy-resolved electron-spin dynamics at surfaces of p-doped GaAs
H. C. Schneider, J. -P. Wuestenberg, O. Andreyev +7
Electron-spin relaxation at different surfaces of p-doped GaAs is investigated by means of spin, time and energy resolved 2-photon photoemission. These results are contrasted with…
Phonon modes of monoclinic BiB3O6
A. Gössling, T. Möller, W. -D. Stein +3
We present a detailed study of the phonon modes of the monoclinic compound BiB3O6 based on polarized reflectivity measurements on single crystals. The spectra are analysed by means…
