MAGNETIC GARNETT SINGLE CRYSTAL, OPTICAL ELEMENT USING THE SAME AND METHOD FOR MANUFACTURING MAGNETIC GARNETT SINGLE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide a magnetic garnett single crystal wherein a lead content is reduced, an optical element using the crystal and a method for manufacturing the magnetic garnett single crystal in respect of the magnetic garnett single crystal grown by a liquid-phase epitaxial (LPE) method, the optical element using the crystal and the method for manufacturing the magnetic garnett single crystal.;SOLUTION: The magnetic garnett single crystal is grown by the liquid-phase epitaxial growth method and expressed by the chemical formula: Bi_xNa_yPb_zM1_3-x-y-zFe_5-wM2_wO₁₂ (wherin, M1 is at least one or more kinds of elements selected from among Y, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu and M2 is at least one or more kinds of elements selected from among Ga, Al, In, Ti, Ge, Si and Pt, 0.5x≤2.0, 0y≤0.8, 0≤z0.01, 0.19≤3-x-y-z2.5, and 0≤w≤1.6).;COPYRIGHT: (C)2006,JPO&NCIPI
