ABSTRACT:
A magneto-optical light switching element comprising islands which are formed from an epitaxial layer on the basis of bismuth-substituted rare earth metal iron garnet, which layer is provided on a magnetically unordered, optically transparent, (111)-oriented garnet substrate, integrated heating resistors being provided on the islands which are surrounded by a coil, the epitaxial layer being grown from a melt which contains lead oxide and boron oxide as a flux, the boron content of the melt used for growing the epitaxial layer being in the range from 12.7 to 25 at % (cation content) and the coil being constructed as an integrated coil.
