Magnetoacoustic Resonance in Yttrium Iron Garnet

Magnetoacoustic Resonance in Yttrium Iron Garnet

Polished spheres of single-crystal yttrium iron garnet were observed to resonate acoustically in the 5 to 30-Mc/sec region by applying a 9300 or a 3000- Mc/sec electromagnetic signal under proper conditions. The ferromagnetic line width of the samples used was 0.5 oe. Observations and conclusions ar...

Zusammenfassung:Polished spheres of single-crystal yttrium iron garnet were observed to resonate acoustically in the 5 to 30-Mc/sec region by applying a 9300 or a 3000- Mc/sec electromagnetic signal under proper conditions. The ferromagnetic line width of the samples used was 0.5 oe. Observations and conclusions are presented. (W.D.M.)
