摘要：
We report the first detection of ferromagnetic resonance in a magnetostrictive amorphous alloy using a fiber interferometer. By measuring the strain at the difference frequency resulting from the application of two rf magnetic fields, we observe a natural (zero field) ferromagnetic resonance near 400 MHz. We discuss novel features of this technique and outline modifications to the existing theory of dynamic magnetostriction suggested by the results.
