Latest Patents
One of Nate's latest patents is an alloy target for manufacturing a magneto-optical recording medium. This alloy target comprises an alloy containing 10 to 50 atom % of at least one rare earth element selected from among Sm, Nd, Gd, Tb, Dy, Ho, Tm, and Er, with the balance consisting substantially of at least one transition metal selected from among Co, Fe, and Ni. The alloy features a mixed structure composed of at least one phase of an intermetallic compound formed by the rare earth element and the transition metal, along with a phase of the rare earth element alone.
Another notable patent is for a rare-earth element/cobalt type magnet powder for resin magnets. This magnetic powder, which is of the samarium/praseodymium/cobalt type and the samarium/praseodymium/neodymium/cobalt type, has specific compositions that are substantially composed of (1-5) single phase. It boasts improved residual magnetic flux density and a high maximum energy product, making it suitable for resin magnets. Additionally, the production cost is lower compared to conventional rare-earth metal/cobalt type magnet powder, as part of the samarium metal has been replaced by praseodymium and neodymium, which are more abundant and less expensive materials.
