Bend Induced Magnetic Bistability in Amorphous Microwires

Magnetic and magneto-optical studies were carried out in microwires that had been subjected to the bending annealing. A previously unobserved effect of bending-annealing-induced magnetic bistability was discovered. This effect is observed only in the region of the sample subjected to bending. The length of the longitudinal region of the sample, in which the effect of induced bistability takes place, depended on the bending radius. In contrast to the classical version of this effect, bending-induced bistability was accompanied by the rapid movement of the longitudinal domain wall in the microwire surface.

Automated summary

This study discovered the previously unobserved effect of bending-annealing-induced magnetic bistability in microwires. The effect is observed only in the region of the sample subjected to bending. The movement of the longitudinal domain wall in the microwire surface accompanies the bending-induced bistability.
