Paramagnetic garnet-type transparent ceramic, magneto-optical material, and magneto-optical device
Provided is a paramagnetic garnet-type transparent ceramic which is a sintered body of a composite oxide represented by formula (1), contains SiO2 in an amount of more than 0% by mass but not more than 0.1% by mass as a sintering aid, has an average sintered particle diameter of 5 [mu] m or more, has a total light transmittance of 84.0% or more at a wavelength of 1064 nm having an optical path length of 25 mm, and has a forward scattering of 0.5% or less. Further, the ceramic has a total light transmittance of 84.0% or more at a wavelength of 1300nm with an optical path length of 25mm and a forward scattering of 0.5% or less, is really transparent, and has high optical homogeneity.
