摘要：

X-band and Q-band nonlinear ferromagnetic resonance spectra of amorphous thin wires are investigated. To achieve the high threshold fields for spin wave instabilities the amplification of the rf magnetic field in the vicinity of a prolate metallic sample is utilized. The butterfly curves for the subsidiary resonance observed in the Q-band indicate that the spin wave linewidth DELTA H//k is independent of k. In the X-band, where the main and the subsidiary resonances coincide, the fine structure of the nonlinear resonance curve is observed.
