Abstract
We observed that the annealing at variable temperature allows to develop amorphous
magnetic microwires with graded magnetic anisotropy. In such microwires, annealed with a
temperature gradient, gradual variation of the hysteresis loops along the microwire length is
observed. The peculiarity of such microwires with graded magnetic anisotropy and rectangular
hysteresis loops is that in such microwires the energy landscape and hence the domain wall
features, such as the domain wall velocity can be effectively controlled. Obtained spatial
distribution of magnetic anisotropy must be attributed to a gradual modification of the
domain structure along the length of the microwires annealed in a temperature gradient.
Accordingly, we propose a rather simple route involving -annealing in a temperature gradient
to design graded magnetic anisotropy in magnetic microwires.
