CAMADA MAGNETO-OTICA,PROCESSO PARA SUA PREPARACAO E MEIO DE REGISTRO MAGNETO-OTICO |
摘要 |
The magneto-optical layer of rare earth metals and transition metals has a gradient of the alloy composition over the layer depth and has a coercive force greater than 8 kOe in the temperature range DELTA T = 100 DEG C around the compensation temperature Tcomp. Production is carried out by a dynamic sputter process in which the substrates to be coated are conveyed past one or more sputter targets which are arranged in a common parallel plane with respect to the path of the substrates. A diaphragm is present between the sputter targets and the substrates. |
