AMORPHES MAGNETOOPTISCHES SPEICHERELEMENT. |
摘要 |
A magneto optical thin film recording medium is disclosed having very high carrier-to-noise ratios and high rotation angles. A transmission electron microscope photomicrograph (at 200,000 X) of one such medium is shown in Figure 1. These are multi-phase amorphous materials having magnetic anisotropy perpendicular to the plane of the thin film. They are produced in a triode vacuum sputtering process at vacuums in the range of 4 x 10<-><3> to 6 x 10<-><4> Torr. By adjusting process parameters such as substrate temperature, anode bias and deposition rate, the properties of the thin film can be altered. |
