Relationship between saturation field and film texture in NiFeCo/Cu giant magnetoresistive multilayers

Abstract

We investigated saturation fields and film textures of NiFeCo/Cu giant magnetoresistive multilayers with weak (1 0 0), weak (1 1 1) and strong (1 1 1) textures. The texture was changed by using various buffer layer materials. For 1 nm thick Cu layers, the saturation field of the multilayers was more than 100 kA/m, and not significantly changed by the texture of the multilayers. While for 2.3 nm thick Cu layers, the saturation field was changed by the texture of the multilayers. The saturation fields were 13.7 kA/m and about 2–3 kA/m for (1 0 0) and (1 1 1) texture, respectively.
