Abstract
We have studied the transmission of millimeter-range electromagnetic waves through (Fe0.82Ni0.18)/V nanostructure. The dependences of the transmission coefficient in the external magnetic field have been measured. The curves have a minimum caused by energy absorption under the ferromagnetic resonance conditions at frequencies 26–35.6 and 37–38 GHz. In a narrow frequency interval near 36 GHz, a complex pattern of resonance phenomena associated with ferromagnetic and spin-wave resonances is observed. We have calculated the field dependence of the transmission coefficient. It has been established that the model of a homogeneous magnetic metal plate used in calculations makes it possible to reproduce some features of resonant changes in the transmission coefficient, which are induced by ferromagnetic and spin-wave resonances.
