Effect of remanent magnetization on exchange biasing in [Pd/Co]×5/FeMn films
The effect of remanent magnetization, which is defined as the initial state of magnetization before FeMn pinning, on exchange biasing in [Pd/Co]×5/FeMn multilayers with perpendicular magnetic anisotropy was investigated. As the Co thickness increases from 0.23 to 0.55 nm in [Pd(0.6 nm)/Co]×5 multila...
