Abstract :
The results of ferromagnetic resonance measurements for microwires in the 75 GHz and 10 GHz frequency bands over a wide temperature range (300 K-0.5 K) are presented. Discussion and analysis of the magnetospectroscopy results are given in the paper. The possible reasons for the magnetoimpedance jump revealed in the vicinity of the low-field area are discussed. The disturbing influence of the microwire element on a high-quality open resonator structure is analyzed. We present here results of a thorough study of the resonance properties of microwires with the following compositions: Co68Mn7Si10 B15; Fe69Si16B10C5; Co75 Si10B15
