Magnetically dead layers at sp-impurity-decorated grain boundaries and surfaces in nickel
Original language description
With the help of ab initio electronic structure calculations, we study segregation of the sp elements (Al, Si, P, S, Ga, Ge, As, Se, In, Sn, Sb, and Te) at the Sigma5(210) grain boundary (GB) and (210) free surface (FS) in fcc FM nickel. Whereas there isa slight enhancement of magnetization at the clean GB and FS with respect to bulk nickel (3?7% and 24%, respectively), most of these impurities nearly kill or substantially reduce the magnetic moments at the FS and, when segregating interstitially at the GB (i.e., Si, P, S, Ge, As, and Se), they produce magnetically dead layers at the boundary. We demonstrate that the existence of magnetically dead layers is a common phenomenon at the sp-impurity-decorated GB and FS in nickel. It is caused by a stronghybridization of sp states of the impurities with the d states of nickel and a redistribution of electron states in both majority and minority bands.
