ABSTRACT:
The present invention relates to a magnetic garnet single crystal prepared by the liquid phase epitaxial (LPE) process and an optical element using the same as well as a method of producing the single crystal, for the purpose of providing a magnetic garnet single crystal at a reduced Pb content and an optical element using the same, as well as a method of producing the single crystal.The magnetic garnet single crystal is grown by the liquid phase epitaxial process and is represented by the chemical formula BixNayPbzM13−x−y−zFe5−wM2wO12(M1 is at least one element selected from Y, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu; and M2 is at least one element selected from Ga, Al, In, Ti, Ge, Si and Pt, provided that 0.5<x≦2.0, 0<y≦0.8, 0≦z<0.01, 0.19≦3−x−y−z<2.5, and 0≦w≦1.6).
