Interfacial properties of [Pt/Co/Pt] trilayers probed through magnetometry

Abstract The magnetic and interface properties of [Pt/Co/Pt] were investigated. First, the magnetic properties were determined from the magnetic dead layer plots, in which the Co layer was considered as two distinct parts representing different magnetic properties. The two parts with low and high t...
