| Popis: | Physical review letters 123(13), 137201-1-137201-7 (2019). doi:10.1103/PhysRevLett.123.137201 We report on the magnetoresistance of textured films consisting of 3d-ferromagnetic layers sandwiched by Pt. While the conventional cos2φ behavior of the anisotropic magnetoresistance (AMR) is found when the magnetization M is varied in the film plane, cos2nθ contributions (2n≤6) exist for rotating M in the plane perpendicular to the current. This finding is explained by the symmetry-adapted modeling of AMR of textured films demonstrating that the cos2θ behavior cannot be used as a fingerprint for the presence of spin Hall magnetoresistance (SMR). Further, the interfacial MR contributions for Pt/Ni/Pt contradict the SMR behavior confirming the dominant role of AMR in all-metallic systems. Published by APS, College Park, Md. |
