物理研究所于1985年1月研制成功一种含　约30%的　-钦铁硼永磁新材料,磁能积达28 MGOe.这种新材料的特点是价格便宜,性能中等,在工业生产上是一种很有发展前途的新材料. 自从1983年底日本研制出　铁硼优质永磁材料以来,我国几个单位于1984年初也先后研制成功.目前国内已有少数 Institute of Physics in January 1985 successfully developed a containing about 30% - Chin Iron boron permanent magnet materials, magnetic energy product up to 28 MGOe. The new material is characterized by cheap, medium performance, in industrial production is A very promising new material since the end of 1983 Japan developed a high-quality iron and boron permanent magnet materials, several units in China has also successfully developed in early 1984. At present there are a handful of domestic
