Magneto-optical material, method for producing same and magneto-optical device
Provided, as a transparent magneto-optical material which does not absorb fiber laser light within a wavelength range of 0.9-1.1 µm and is thus suitable for constituting a magneto-optical device such as an optical isolator wherein the formation of a thermal lens is suppressed, is a magneto-optical material which is composed of a transparent ceramic that contains a complex oxide represented by formula (1) as a main component, or which is composed of a single crystal of a complex oxide represented by formula (1). Tb 2x R 2(2-x) O 8-x (1) (In the formula, 0.800 < x < 1.00, and R represents at least one element selected from the group consisting of silicon, germanium, titanium, tantalum, tin, hafnium and zirconium (excluding the cases where R represents only silicon, germanium or tantalum).)
