Occurrence of the magnetic polarization on an iron adatom on a matrix of transition metals of the first row

Abstract

We use a simple model developed by Clogston [1] to study the occurrence of magnetic polarization on an iron atom in different surroundings. We discuss the cases of an adatom or a substitutional impurity. It is shown that the polarization appears more easily when an atom of iron goes from a bulk substitutional place to a surface substitutional place and in a same way when it goes from this place to an adsorbed place. Experimental results are awaited for a more elaborate theoretical study
