Multidomain Structures in Magnetic Microwire

We report investigations on temperature-induced transformation of magnetic domain structures in the Fe-rich amorphous glass-covered microwires. The images of domain structures and magnetization reversal process were registered by means of magnetooptical Kerr microscopy. The coexistence of two different types of surface domain structures with helical magnetization components has been found. The obtained results discussed in the frame of the model supposed the stress influence on the domain structure.
