Abstract:

Magnetostatic modes of resonance were studied in a rectangular slab of single-crystal yttrium iron garnet YIG. Two moveable fine-wire transducers on opposite faces of the normally-magnetized slab allowed excitation and detection of spatially localized resonances at S-band frequencies. The strength of the detected signal was found to be dependent on the lateral displacement of the sample relative to the transducers. Multiple transmission peaks corresponding to multiple modes of resonance exhibited symmetry about the middle of the crystal. The distance of these peaks from the middle of the crystal increased as the excitation frequency was increased, or as the magnetic field was decreased.
