Features of the magnetophotonic crystal spectrum in the vicinity of ferromagnetic resonance

Abstract We theoretically investigate a special phenomenon which reveals in a transmission spectrum of the magnetophotonic crystal. We call it “secondary transmission band” (STB). These bands are located in the main stopband in the vicinity of the ferromagnetic resonance. It is shown that the nature of STB is caused by Wolf–Bragg resonance. The possible methods to control bands amount, their maximum amplitude and their central frequency position are under discussion.
