Abstract (en)
[origin: US4698281A] The invention relates to a magnetic material containing either one or more rare earth elements, chosen from among lutetium, thulium and ytterbium, or yttrium. It also relates to a magnetic film with a high Faraday rotation constituted by a substrate coated with an epitactic layer of a magnetic material of the aforementioned type. The process for the production of such a magnetic film involves the deposition of a garnet film by liquid phase epitaxy on a substrate, use being made of an epitaxy bath containing gadolinium oxide, praseodymium oxide, and at least one oxide of a metal M, bismuth oxide, iron oxide, gallium oxide and/or aluminium oxide and a solvent incorporating lead oxide and boron oxide.
