Abstract

The electronic structures of a (001) surface of crystalline Dy2F e14B and Nd2 Fe14 B have been studied and the crystal field parameters at the rare-earth sites have been estimated by using first principles calculations. It is shown that Dy or Nd ions at the surface exhibit an in-plane magnetic anisotropy and can be nucleation sites of magnetization reversal.
