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: Co/sub 68/Mn/sub 7/Si/sub 10/B/sub 15/; Fe/sub 69/Si/sub 16/B/sub 10/C/sub 5/; Co/sub 75/Si/sub 10/B/sub 15/.
