摘要: Composite material for magnetooptic recording, comprising a thin layer deposited on non-magnetic solid substrate. The said is polycrystalline consisting of microcrystals having structure vacant-site spinel ferrite, based iron, cobalt and transition metals. By virtue particular process producing the layers, enabling especially size crystallites to be increased, it possible optimize magnetic properties obtain layers having, example, remanent Faraday rotation coercive field which are greater, respectively, than 1 degree per micron 1000 Oe field.
