Magnetoelectric classification of skyrmions
Sayantika Bhowal, Nicola A. Spaldin
We develop a general theory to classify magnetic skyrmions and related spin textures in terms of their magnetoelectric multipoles. Since magnetic skyrmions are now established in i…
Longitudinal and transverse electron paramagnetic resonance in a scanning tunneling microscope
Tom S. Seifert, Stepan Kovarik, Dominik M. Juraschek +3
Electron paramagnetic resonance (EPR) spectroscopy is widely employed to characterize paramagnetic complexes. Recently, EPR combined with scanning tunneling microscopy (STM) achiev…
Self-interaction effects in (Ga,Mn)As and (Ga,Mn)N
Alessio Filippetti, Nicola A. Spaldin, Stefano Sanvito
The electronic structures of Mn-doped zincblende GaAs and wurtzite GaN are calculated using both standard local-density functional theory (LSDA), and a novel pseudopotential self-i…
