The Features of Standing Spin Wave’s Spectra in Granulated and Gradient Co-Based Multilayer Films

The [СоxNi1–x]N and [СоxP1– x]N films with composition gradient were prepared by electroless deposition. The [(Co40Fe40B20)X(SiO2)100-X/α-Si:H]N and [(Co40Fe40B20)X(SiO2)100-X/SiO2]N films were prepared by the ion-beam sputtering. It is found that the spin–wave resonance spectrum in these films is characterized by anomalous dependences of resonance fields of spin–wave modes Hr on the mode number: Hr(n) ~ n, Hr(n) ~ n2/3.
