Abstract

We report an observation of the instability of the ferromagnetic resonance spectrum in [Mn{(R/S)-pn}2]2[Mn{(R/S)-pn}2H2O][Cr(CN)6] single crystals initiated by the microwave irradiation. The value of the threshold microwave power leading to the instability, Pth = 0.2-0.9 mW, depends on the relative orientation of the easy magnetization axis of the crystal and magnetic field. It was found that in the region of the high microwave power, P > Pth, the spin-wave bi-stability develops.
