Engineering of domain wall propagation in magnetic microwires with graded magnetic anisotropy

[EN] We report on the influence of graded magnetic anisotropy designed by stress-annealing of magnetic microwire at variable annealing temperature on domain wall propagation. We found that the domain wall propagation in a medium with graded magnetic anisotropy is substantially nonuniform. Domain wal...

We found that the domain wall propagation in a medium with graded magnetic anisotropy is substantially nonuniform. Domain wall can be trapped in the microwire region with strong enough stress-annealing induced magnetic anisotropy. On the other hand, faster domain wall propagation and a decrease in the domain wall length are observed in the region with moderate stress-annealing induced magnetic anisotropy. Beneficial effect of stress annealing on the domain wall dynamics is associated with the induced transverse magnetic anisotropy in the outer domain which affects the travelling domain wall in a similar way as application of transversal bias magnetic field. Observed decreasing of the half-width of the electromagnetic force (EMF) peak in stress-annealed microwires can be associated to the decreasing of the characteristic domain wall length.This work was supported by the Spanish MCIU, under PGC2018099530-B-C31 (MCIU/AEI/FEDER, UE), by the Government of the Basque Country, under PIBA 2018-44, PUE_2021_1_00 09 and Elkartek (CEMAP and AVANSITE) projects, and by the University of Basque Country, under the scheme of "Ayuda a Grupos Consolidados"(Ref.: GIU18/192) and COLAB20/15 project.
