Effects of the V2O3 structural phase transition on the magnetic properties of an amorphous magnetic thin film of CoFeB in contact with it. By means of temperature dependent Kerr effect characterizations, in this paper is proven that crossing the V2O3 structural phase transition induces reproducible and reversible changes to CoFeB magnetic properties, especially to its coercive field.

A fine analysis of local structure and magnetic response of Co films intercalated between Graphene and Iridium (Gr/Co/Ir systems) has revealed how the response of such systems to annealing depends on the Co thickness.
