On the rich magnetic phase diagram of (Ni, Co)-Mn-Sn Heusler alloys
Anna Grünebohm, Heike C. Herper, Peter Entel
We put a spotlight on the exceptional magnetic properties of the metamagnetic Heusler alloy (Ni,Co)-Mn-Sn by means of first principles simulations. In the energy landscape we find…
Relativistic theory of spin relaxation mechanisms in the Landau-Lifshitz-Gilbert equation of spin dynamics
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
Starting from the Dirac-Kohn-Sham equation we derive the relativistic equation of motion of spin angular momentum in a magnetic solid under an external electromagnetic field. This…
On the origin of perpendicular magnetic anisotropy in strained Fe-Co(-X) films
Ludwig Reichel, Alexander Edström, Darius Pohl +4
Very high magnetic anisotropies have been theoretically predicted for strained Fe-Co(-X) and indeed several experiments on epitaxial thin films seemed to confirm strain induced ani…
Electronic structure of (Ga,Mn)As revisited
J. Kanski, L. Ilver, K. Karlsson +4
The detailed nature of electronic states mediating ferromagnetic coupling in dilute magnetic semiconductors, specifically (Ga,Mn)As, has been an issue of long debate. Two confronti…
Structural and magnetic properties of Co-N thin films deposited using magnetron sputtering at 523 K
Nidhi Pandey, Mukul Gupta, Rachana Gupta +3
In this work, we studied cobalt nitride (Co-N) thin films deposited using a dc magnetron sputtering method at a substrate temperature (\Ts) of 523\,K. We find that independent of t…
Magnetic Effects in the Paraxial Regime of Elastic Electron Scattering
Alexander Edström, Axel Lubk, Ján Rusz
Based on a recent claim [Phys. Rev. Lett. 116, 127203 (2016)] that electron vortex can be used to image magnetism at the nanoscale in elastic scattering experiments, using transmis…
