Effect of Sn-doped Ge insertion layers on epitaxial growth of ferromagnetic Fe3Si films on a flexible substrate

Abstract

By an insertion of a Ge(Sn) layer and its CMP treatments, we have improved the crystalline and magnetic characteristics of one of the Heusler-compounds, Fe3Si, on (111)-oriented Ge on a flexible substrate. This work is a first step of high-performance flexible spintronics for flexible system-in-display devices.
