MOKE studies of magnetic microwires with longitudinally distributed properties

We report the stress-annealing induced distribution of the helical magnetic structure in the magnetic microwires. The longitudinal space distribution of the magnetic anisotropy originated by stress-annealing at variable annealing temperature is the reason of the observed effect. We have found that the helicality of magnetic structure in different points of the microwire could be controlled by the external mechanical torsion stress.

Automated summary

This article reports the distribution of helical magnetic structure induced by stress annealing in magnetic microwires. The longitudinal spatial distribution of magnetic anisotropy, originated from stress annealing at various annealing temperatures, is responsible for the observed effect. It has been found that the helicality of magnetic structure in different points of the microwire can be controlled by external mechanical torsion stress.
