Effect of annealing on carrier density and Curie temperature in epitaxial (Ga,Mn)As thin films

B. Sorensen, J. Sadowski, R. Mathieu +2

We report a clear correspondence between changes in the Curie temperature and carrier density upon annealing in epitaxially grown (Ga,Mn)As layers with thicknesses in the range bet…

Modeling the actinides with disordered local moments

Anders M. N. Niklasson, John M. Wills, Mikhail I. Katsnelson +3

A first-principles disordered local moment (DLM) picture within the local-spin-density and coherent potential approximations (LSDA+CPA) of the actinides is presented. The parameter…
