The orange peel coupling is suppressed dramatically when an oxide layer (OXL) is inserted into the free/pinned FM layers due to smoother surface roughness at the interface. Hint decreases with increasing oxygen exposure dose of the free/pinned FM layers to pure O2 gas. And it is found that Ruderman-Kittel-Kasuya-Yoshida exchange coupling dominates in OXL spin valves due to smoother surface roughness and enhanced specular electron scattering at the interface between OXL and pinned/free FM layers, which also results in enhancement of magnetoresistance effect. © 2001 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/83118||ISSN:||00036951||DOI:||10.1063/1.1421228|
