[0012] specific implementation plan
[0013] The process of preparing the magneto-optical target is as follows:
[0014] Process 1 Raw material treatment and batching: chemically treat the surface of industrial pure iron, then refine terbium, light rare earth, and iron in a magnetic suspension furnace; at the same time, carry out appropriate surface treatment on cobalt; finally, batching under the protection of inert gas ; The ingredient elements and components of various targets are consistent with the above-mentioned composite targets. The base target alloy is smelted by magnetic levitation technology, and the alloy composition of the base target 1 is iron-cobalt (FeCo) alloy. Cut pure terbium 2 (Tb) and light rare earth 3 (LRE) wires into segments or disks, and symmetrically inlay them in the circular area with the largest etching of the iron-cobalt alloy-based target 1 to make a composite target, such as figure 1 with figure 2 As shown, the composition of the target ca...
