Research Abstract

We investigate and discuss the magneto-crystalline anisotropy (MCA)of Fe(13-layer)/GaAs(001)interface. Purpose of this work is theoretical design of the highly spin-polarized spin injection devices into the non-magnetic semiconductor with perpendicular magnetization. We obtained perpendicular MCA both for As and Ga terminations. MCA energies are 0. 898 [mJ/m^2] for As termination and 0. 469 [mJ/m^2] for Ga termination. However, due to the large demagnetizing filed energy of Fe-layer, the thin Fe-layer less than 1nm will be needed to obtain the perpendicular magnetization at the Fe/GaAs interface.
