Magneto=optical material used in storage media - based on multicomponent system contg. copper-chromium chalcogenide

摘要

A magneto-optical material (I), based on a multi-component system (II), contains one element from the chalcogens. The novelty is that (II) is a Cu-Cr chalcogenide of compsn. CuCr2X4, where X is S, Se or Te. ADVANTAGE - (I) shows a relatively large magneto-optical effect at room temp. and therefore can be used in storage media.
