Abstract

See full text

An object of the present invention is to provide a magneto-optical material capable of exhibiting the Faraday effect even though no magnetic field is applied. The magneto-optical material of the present invention has a nanogranular structure in which magnetic nanoparticles are dispersed in a fluoride matrix, and can exhibit Faraday properties without requiring the application of a magnetic field because the magnetic nanoparticles are configured by a magnetic material that has residual magnetization and consists of any of a Fe—Pt alloy, a Co—Pt alloy, a Fe—Co—Ni—Al alloy, a Co ferrite, or a Ba ferrite.
