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

force 898 … 963 A/m), which enables holding of particles of abrasive loose material on working surfaces.
With local magnetization of the working surfaces, a relatively small volume of material must be brought to saturation, since the average value of the nominal contact area between the wheels and rails is about 1·10-4 M2 .
Fig. 1 shows the amplitude variation graphs of the horizontal (Hx) and vertical (Hy) components of the magnetic field, depending on the depth of magnetization by magnets of

An optical probe current sensor module using the Kerr effect of exchange-coupled magnetic film has been fabricated and applied to switching current measurements for IGBT used for the DC-DC converter and the DC-AC inverter of EV/HEV. Since the sensor module using the Kerr effect of the single domain exchange-coupled magnetic film utilizes magnetization rotation only, Barkhausen noise due to domain wall pinning can be excluded. The current sensor consists of a Laser-diode, a polarizer, a Fe-Si/Mn
