摘要: Summary form only given. Current perpendicular to plane (CPP) GMR is being studied as the possible candidate for high density recording applications. One of advantages CPP that it allows elimination insulating gap layer in read head. However, most recently reported MR ratio sensors about 2.3% even specular spin-valves. The performance spin-valves has be increased substantially before can applied heads. ways increase confine electrons at active layers so they will experience more spin-dependent scattering interface. This realized by either putting oxides outer boundary free and pinned or using metallic multiple layers. former already been explored current spin valves reflective latter relatively new systems. If surface individual sufficiently smooth, should highly electron mirrors Bragg reflectors. Based on this background, work, we have investigated effect (CoFe/Cu)/sub N/ multilayers a dual with nano-oxides reflection
