Abstract

High frequency resonance technique was applied to study of magnetic multilayer Co/Cu films possess the giant magnetoresistance. The results of the ferromagnetic resonance study in 60GHz-80GHz and 1OGHz bands revealed low temperature changes of g-factor after annealing and a very small value of high frequency saturation magnetization. An abrupt change of the specimen impedance was registered in low field low field range for 10GHz. The static magnetic characteristics as hysteresis and magnetoresistance loops were obtained at room temperature for the planar orientation of external magnetic field.
