RFe＿（10．5）V＿（1．5）N＿x化合物的结构和内禀磁性研究

STUDY ON THE STRUCTURAL AND MAGETIC PROPEERTIES OF

系统地研究了ＲＦｅ＿（１０．５）Ｖ＿１．５）Ｎｘ（Ｒ＝Ｙ，Ｃｅ，Ｎｄ，Ｓｍ，Ｇｄ，Ｔｂ，Ｄｙ，Ｈｏ，Ｅｒ）化合物的结构和内禀磁性，并与相应的ＲＦｅ＿（１０．５）Ｖ＿１．５）Ｎｘ化合物进行了比较。同ＲＦｅ＿（１０．５）Ｖ＿１．５）Ｎｘ化会物相比，由于ｖ含量低，ＲＦｅ＿（１０．５）Ｖ＿１．５）Ｎｘ化合物具有较高的居里温度和饱和磁化强度。ＮｄＲＦｅ＿（１０．５）Ｖ＿１．５）Ｎｘ的易磁化方向沿着ｃ轴，１．５Ｋ和室温的各向异性场分别为１８６和１０２ｋＯｅ，室温饱和磁化强度为σｓ＝１３９．１ｅｍｕ／ｇ，居里温度Ｔｃ＝７８４Ｋ，是很有前途的实用永磁化合物。

systematic study on the structural and magnetic properties of the ReFe_(10.5) V_(1.5)N_xseries,where R=Y,Ce, Nd,Sm,Gd,Tb,Dy,Ho.Er.has been carried outby X-ray diffraction and magnetic measurements.RFe_(10.5) V_(1.5)N_x compounds show ahigher Curie temperature and a larger saturation magnetization due to the lower co-ntent of V compared with RFe_(10.5) V_(1.5)N_x In NdFe_(10.5) V_(1.5)N_x,the c-axis is the easy axisfrom 0 K to Tc,tlie anisotropy field is up to l85 kOe at 1.5 k and 102 kOe at roomtemperature with a combination of a high Curie temperature of 784 K and a largeroom temperature saturation magnetization of 139.1 emu/g,the intrinsic magneticproperties are favourable for permanent magnet applications。
