Observation of nonlinear FMR in amorphous microwires using standard x-band spectrometer

Original language description

Experimental technique for investigation of nonlinear ferromagnetic resonance in thin metallic wires is described. It uses a simple home-made X-band FMR spectrometer with static magnetic field and microwave electric field parallel to the wire. Electric polarization of the wire induces microwave current and large circumferential AC magnetic field on the wire surface. This reduces the critical power for the onset of nonlinear effects. Moreover, in Fe-rich amorphous metals the condition of coincidence of the main and the subsidiary resonances is satisfied at X-band frequencies which further reduces the critical field for the onset of insta-bility. Then the microwave power of few mW is sufficient for observation of nonlinear FMR. The nonlinear resonance curves of very thin wires show well distinguished fine structure with the period inversely proportional to the wire diameter.
