Electronic and Magnetic Properties of Ferromagnet-Semiconductor Heterostructure Systems
To stimulate corresponding experimental work the magnetic circular dichroism has been investigated for the L 2,3-edges absorption spectra of Ga as well as As. In all cases the circular dichroism was found to be pronounced enough to be detectable.
Investigations on the magneto-crystalline anisotropy energy revealed that all of the studied systems should show a perpendicular anisotropy. Calculations of the spin-orbit induced orbital magnetic moment in a spin-resolved way allowed us to check the correlation of this quantity with the magneto-crystalline anisotropy energy. It was found that the relationship suggested recently by van der Laan is quite well fulfilled.
