Magnetic garnet material, Faraday rotator, optical device, manufacturing method, and single-crystal film of bismuth-substituted rare earth iron garnet single crystal film

摘要

PROBLEM TO BE SOLVED: To provide a magnetic garnet maintaining a magnetic hysteresis of a square Faraday rotation angle in the temperature range in which a Faraday rotator is used.;SOLUTION: The magnetic hysteresis of the Faraday rotation angle is maintained in a square shape in the temperature range in which the Faraday rotator is used by regulating the variation of a Pt concentration to be ≤200%.;COPYRIGHT: (C)2004,JPO
