Features of the AMR Effect in Magnetic Strips with Perpendicular Anisotropy

Abstract

A theoretical model is proposed for structures of collective micromagnetic spin in magnetoresistive FeNiCo nanostrips with perpendicular anisotropy. Atypical dependences of the magnetoresistance on the magnitude of the external field obtained experimentally indicate there is a complex domain structure in each sample. The curves of the AMR effect, calculated in accordance with this model, are in quantitative agreement with the experimental results for the above samples, while calculations using the specialized OOMMF package show only qualitative similarities.
