摘要
A thin YIG layer (3) over a large area (2a) of nonmagnetic liq.-phase-epitaxial GdGaG substrate (2) carries electrodes (5) 30 microns wide and 3 mm long. A resonator (6) 5 mm long, 2 mm wide and 0.5 mm thick is cut with a diamond blade from the wafer. The other large surface (2b) of monocrystalline GdGaG is coated with 10 microns of epoxy resin (8) to absorb the acoustic waves by internal friction. USE/ADVANTAGE - In e.g. thin-film garnet microwave oscillators, the spurious mode is suppressed over wide range of frequencies, and undesirable degradation of resonance properties is avoided.
