Résumé

Abstract: Microwave magnetic impedance spectra are obtained for (Formula presented.) (x = 0.46–0.88) films in a DC magnetic field of 0‒0.7 T. The modulus of microwave impedance in films with x = 0.76 is found to fall by as much as 6% upon magnetization. The maximum negative microwave magnetic impedance of the films is established along with its shift from 2.2 to 0.4 GHz as x rises. A striped magnetic structure with oppositely directed magnetizations of neighboring stripes is observed.
