Abstract:
1. A method of producing a garnet single crystal comprising: preparing a solution containing B, Na, and Bi, wherein: a B blend ratio “x” (in mol %), a Na blend ratio “y” (in mol %), and a Bi blend ratio “z” (in mol %) satisfy the relations of: dissolving in the solution containing B, Na, and Bi at least Fe, and optionally one or both of Ga and Al, at a blend ratio “r” of Fe, Ga, and Al of 9.0 mol % or more to 25.5 mol % or less; and then growing a garnet single crystal using the solution; wherein a thickness of the garnet single crystal is from 50 μm or more to 570 μm or less.
