Abstract :
We report investigations on influence of high-frequency electric current on surface magnetization reversal and surface domains nucleation in amorphous glass covered microwires. Magneto-optical Kerr magnetometry and microscopy have been used. A strong change of surface magnetization reversal and the transformation of the surface domain structure induced by electric current within a frequency range of 100 Hz-15 MHz have been found.
