Abstract

In order to study the temperature dependence of the magnetic anisotropy energy of thin ferromagnetic films from first principles we combined the relativistic extension of the disordered local moment approach with the screened Korringa-Kohn-Rostoker technique for layered systems. We first apply the new method for a Fe monolayer on a Cu(1 1 1) surface and a Co monolayer on a Cu(1 0 0) surface referring to an out-of-plane and an in-plane magnetization, respectively. Interestingly, the magnetic anisotropy energy follows a remarkably different temperature dependence for these two cases. This different behavior is also demonstrated in terms of the relationship between the magnetic anisotropy energy and the average magnetization.
