摘要

Non-reciprocal switching circuit element comprises a magnetic component and a magnet for applying a direct current magnetic field on the magnetic component. The magnetic component has a ferromagnetic half intensity width for resonance of approximately 200 A/m or less. Preferred Features: The magnetic component is a single crystal material, preferably Y3Fe5O12 containing Bi, Ga, Al, In, Se or a rare earth. The ferromagnetic half intensity width for resonance is 180 A/m or less.
