Abstract
PURPOSE:To secure a stable isolation value without being affected by the temperature dependence of both the Faraday rotation coefficient and a laser oscillation wavelength by a method wherein Tb, Pr, Bi and Fe5O2 are contained in a position 24c and quantities of Tb, Pr and Bi are specified. CONSTITUTION:This composition is expressed by a chemical formula of TbxPryBi3-x-yFe5O12. For example, a magnetic garnet single-crystal film with a thickness of 450mum whose chemical formula is Tb2.13Pr0.15Bi0.72Fe5O12 having no mismatched lattice constant is formed on a non-magnetic calcium-magnesium- zirconium-substituted gadolinium-gallium-garnet substrate whose lattice constant is 12,490Angstrom by a liquid-phase epitaxial method by using a fusing agent which is based on lead oxide, bismuth oxide and boron oxide and which is held in a platinum crucible at 790 deg.C. The Faraday rotation coefficient at 45 deg. of this garnet film displays a variation of 0.5% with reference to a value at 25 deg. at a wavelength of 1.3mum and at 0 deg.C and 50 deg.C. Accordingly, it is possible to secure an isolation of 48 dB.
