Magnet With High Intinsic Coercivity Xiao Yaofu,Zhang Zhengyi Abstract High Hc (>30KOe)has 'been obtained in Sm (Co Cu Fe Zr)7.ma- gnet after aging at 850C for a long period of time.Coercivity,initial magnetizalion curves,magnetic domain patterns,microstructures and microstres of the diffrent aging time at 850C are Studied using magnetic measurement,Kell technical and transmisson electron mieroscopy.The action of "2m phase,zonal structure and grain boundary precipitates on domain walls are discussed and a machanism of heterogeneous pinning at the high coercivity is suggested. 34今 考 文 献 〔 〕 , 卜 〔 〔 〕 , 工 〔 〕 , , 、 〔 硕 , 牙 〔 〕 , 砚 一 〔 〕 小 一 一 〔 〕 玉 乒 硕 一 〔 〕 砚 梦 〕 张 正 义 , 肖耀福 等 , 金 属材料研究 第九卷 第一期 〔 〕 , 〔 〕 , , 一 , ‘ , ’ 德 爪 以 , ‘ 乓一 亡 ℃ , , , ℃ , ’ ”
