Ferromagnetic Resonance and Interlayer Exchange Coupling in (Fe/Cr)n Superlattices

The electromagnetic wave transmission in samples of Fe/Cr superlattices has been studied, for which the ferromagnetic resonance is observed in the magnetically unsaturated state. The transmission experiments have been performed at room temperature and at frequencies between 26 and 38 GHz. Ferromagne...

Zusammenfassung:The electromagnetic wave transmission in samples of Fe/Cr superlattices has been studied, for which the ferromagnetic resonance is observed in the magnetically unsaturated state. The transmission experiments have been performed at room temperature and at frequencies between 26 and 38 GHz. Ferromagnetic resonance spectra were measured. The interlayer exchange constants were estimated using magnetization curves. Ferromagnetic resonance spectra of acoustic branch were calculated using the values of exchange constants. The experimental and calculated resonance spectra have been compared.
