Magneto-optical study of microwire in presence of magnetic field of super high frequency
Abstract
The work is dedicated to the magneto-optical Kerr effect (MOKE) study of the magnetization reversal in the microwire in the presence of super high frequency (SHF) circular magnetic field. This study is important for elucidation of functioning of sensor based on giant magneto-impedance (GMI) effect. Magnetic domains images have been obtained using MOKE polarizing microscopy. Hysteresis loops were obtained as a result of images processing. It was found that SHF magnetic field induces strong change of the mechanism of magnetization reversal.
