Abstract

A study on Ni-transition metal alloys was carried out to theoretically understand the magnetic anisotropy in antiferromagnetic (AFM) and its extension to ferromagnetic/antiferromagnetic (FM/AFM) interfaces. First, the magnetic anisotropy in the ferromagnetic Ni_xFe_1-x alloy system with x=0.5 and 0.75 was examined. Following this, first-principles calculations were made for the magnetic anisotropy of Mn-based antiferromagnetic alloys. Finally, the NiFe/NiMn superlattice structure was studied to examine the magnetic structure of an interface between ferromagnetic NiFe and antiferromagnetic NiMn. Nonvanishing moments of Ni were observed between the ferromagnetic Fe layer and antiferromagnetic Mn layer.
