Abstract

To confirm the origin of the exchange field from nano-oxide layer (NOL), the detailed analyses of the magnetization curve and the temperature dependence on magnetization for the Co_1-xFe_x-NOL inserted samples were investigated. The room temperature NOL exchange biasing superimposed on AFM exchange bias in specular spin-valve (SPSV) is also considered to realize CIPGMR (current in plane giant magnetoresistance) with higher sensitivity and a more stable pinned layer for high density magnetic recording head.
