Interlayer diffusion and specularity aspects of amorphous CoNbZr based spin valves

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Among various factors that affect thermal degradation in spin valves (SV), Mn diffusion into pinned and Cu layers appears to be the most harmful to magnetoresistance (MR) and exchange coupling. The effects of CoNbZr (CNZ) film as underlayer and capping layer on thermal stability and Mn diffusion behavior were investigated at elevated temperatures in CNZ 2 nm (or Ta 5 nm)/CoFe/Cu/CoFe/IrMn/CNZ x nm (or Ta 5 nm) stacks. The normalized MR ratio and Hex with respect to annealing time were evaluated.
