摘要： The present invention relates to a magnetic garnet single crystal and a Faraday rotator using the magnetic garnet single crystal and the object of the present invention is to provide a magnetic garnet single crystal which suppresses a generation of crystal defects and a Faraday rotator which improves an extinction ratio. A magnetic garnet single crystal grown by a liquid-phase epitaxial growth method and having the general formula represented byBi a Pb b A 3-a-b Fe 5-c-d B c Pt d O 12 is used, wherein A is at least one kind of element selected from Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, B is at least one kind of element selected from Ga, Al, Sc, Ge and Si, and a, b, c and d are represented by 0
