Low magnet-saturation bismuth-substituted rare-earth iron garnet single crystal film

摘要

A low magnetic saturation type bismuth-substituted rare-earth iron garnet crystal film of the invention is grown on a substrate of (111) garnet single crystal (GdCa)3(GaMgZr)5O12 by using a liquid phase epitaxial method. This single crystal has a lattice constant of 1.2497+/-0.0002 nm and has a chemical structural formula expressed by Tb3-xBixFe5-y-zGayAlzO12 wherein x has the range 1.25<x<1.40, y+z has the range 0.50<y+z<0.65, and z/y has the range 0.45<z/y<0.75.
