Abstract :
We report investigations on crossed magnetic field-induced transformation of surface domain structure in amorphous glass covered microwires. The study has been performed by a magneto-optical Kerr effect technique using optical microscopy. The existence of elliptic domain structure has been demonstrated experimentally. The formation of the domain structure with periodically inclined domain walls caused by the circular magnetic field was found in the surface of microwires.
