Title:
MAGNETIC GARNET SINGLE CRYSTAL AND YIG DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/019507
Kind Code:
A1
Abstract:
A YIG device comprises a resonator composed of a spherical YIG crystalline body (16) of a yttrium iron garnet single crystal in which part of yttrium atoms are replaced with gadolinium atoms, and a magnetic field applying means (26) for applying a magnetic field to the YIG crystalline body (16) to resonance it. Thus, a YIG device having a small magnetic resonance half peak width and a large limit power with which resonance saturation occurs can be produced.
