Reorientation Transition in Single-Domain (Ga,Mn)As
K-Y. Wang, M. Sawicki, K. W. Edmonds +5
We demonstrate that the interplay of in-plane biaxial and uniaxial anisotropy fields in (Ga,Mn)As results in a magnetization reorientation transition and an anisotropic AC suscepti…
On the symmetry of a Preisach map
Marek W. Gutowski
At the very heart of the successful phenomenological model of magnetic hysteresis there is the so called Preisach distribution. In the existing literature it is implicitly assumed,…
Enhanced angular overlap model for f-electron non-metallic systems
Z. Gajek
An efficient method of interpretation of the crystal field effect in non-metallic f-electron systems, the {\it enhanced angular overlap model} (EAOM), is presented. The method is e…
Influence of annealing parameters on the ferromagnetic properties of optimally passivated (Ga,Mn)As epilayers
V. Stanciu, O. Wilhelmsson, U. Bexell +5
The influence of annealing parameters - temperature and time - on the magnetic properties of As-capped (Ga,Mn)As epitaxial thin films have been investigated. The dependence of the…
Different ways of dealing with Compton scattering and positron annihilation experimental data
G. Kontrym-Sznajd, M. Samsel-Czekala
Different ways of dealing with one-dimensional (1D) spectra, measured e.g. in the Compton scattering or angular correlation of positron annihilation radiation (ACAR) experiments ar…
Influence of experimental noise on densities reconstructed from line projections
M. Samsel-Czekala, L. Boguszewicz
The influence of experimental noise on densities rho(p) reconstructed by the Cormack method from their line projections, e.g. 2D ACAR spectra, is investigated. Simulations of stati…
