DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel permanent magnet material containing rare earth elements. Many studies have been carried out on alloy systems consisting of rare earth elements and transition metal elements, and among these, alloy systems consisting of rare earth elements (2) and CO are currently being used as practical materials. Specifically, it is an RCO type alloy and a Cu-added Rcoty type alloy, and its compositional formula is in the range of RCO8%RCO7.

In R-Co alloys, as the specific gravity of CO to R increases, the saturation magnetization strength (4πIs) increases, and the magnetization increases with hanging energy, which is a typical characteristic of magnets. Therefore, research has shifted from the specific KtiRCOs system to the Ijscoty system, which has higher saturation magnetization. Furthermore, if the composition is set to the Coricll side, the saturation magnetization increases, but on the other hand, a high coercive force cannot be obtained, perhaps because the anisotropic magnetic field that affects the coercive force decreases, and so far, the possibility of using it as a magnetic material has been limited. has not been found. Therefore, the Ministry of the Invention and others conducted intensive research on the R-Co-X system and R-CG-Fe-X system that can satisfy the basic physical property values as a magnet material in the Corich side composition system with higher saturation magnetization. They discovered that the anisotropic magnetic field (HA) can be improved in compositions with high saturation magnetization (4π!g) by adding poron as X, and found that it can be used as a sufficient magnetic material.
