PARAMAGNETIC GARNET-TYPE TRANSPARENT CERAMIC, MAGNETO-OPTICAL DEVICE, AND PRODUCTION METHOD FOR PARAMAGNETIC GARNET-TYPE TRANSPARENT CERAMIC
A paramagnetic garnet-type transparent ceramic that exhibits a high laser damage threshold, said ceramic being a sintered body of a Tb-containing rare earth-aluminum garnet represented by formula (1), and being characterized in that the average sintered grain size is 10-40 µm, and the insertion loss at a wavelength of 1,064 nm in the optically effective region along the length direction of a 20 mm-long sample is 0.05 dB or less. Formula (1): (Tb1-x-yYxScy)3(Al1-xScz)5O12(In the formula, 0 ≤ x < 0.45, 0 ≤ y < 0.08, 0 ≤ z < 0.2, and 0.001 < y+z < 0.20.)
