Abstract

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).TbRO  (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)).
