PARAMAGNETIC GARNET-TYPE TRANSPARENT CERAMIC, MAGNETO-OPTICAL MATERIAL, AND MAGNETO-OPTICAL DEVICE
The paramagnetic garnet-type transparent ceramic a sintered object of a composite oxide represented by formula (1), (Tb1−x−yYxScy)3(Al1−zScz)5O12 (0.05≤x<0.4, 0≤y<0.004, 0.6≤1−x−y<0.95, 0≤z<0.004, and 0.001<0.005), which contains SiO2 as a sintering aid in an amount larger than 0 mass % but not larger than 0.1 mass %, and having an average sinter-grain diameter of 5 μm or larger. The transparent ceramic has a total light transmittance of 84.0% or greater and a forward scatter of 0.5% or less at an optical path length of 25 mm and a wavelength of 1,064 nm and has a total light transmittance of 84.0% or greater and a forward scatter of 0.5% or less at an optical path length of 25 mm and a wavelength of 1,300 nm. In the formula (1).
