Abstract
It is an object of the present invention to provide a magnetic garnet single crystal capable of reducing the optical loss of the resulting rotator even when the magnetic garnet single crystal is grown using a solvent containing Na by the liquid phase epitaxial process, as well as a Faraday rotator using the same. A magnetic garnet single crystal represented by the chemical formula BiNaM1M2FeMgM3O(M1 is at least one element or more selected from Y, Eu, Gd, Tb, Dy, Ho, Yb and Lu; and M2 is at least one element or more selected from Ca and Sr; M3 is at least one element or more selected from Si, Ge, Ti, Pt, Ru, Sn, Hf and Zr, provided that 0.60<α≦1.50, 0<β≦0.05, 1.35<3−α−β−γ<2.40, 0≦γ≦0.10, 0≦δ≦0.10, 0<ε≦0.10, 0<γ+δ≦0.10, 0<δ+ε≦0.10).
