摘要
The dramatic changes in the magnetic properties observed in the R2Fe17 alloys upon nitrogen absorption have also been observed in the NdFe10T2Nx (T = Mo,V). The nitrides, prepared at T = 773 K and 2 1/2 atm pressure of N2, showed an increased anisotropy H(A) > 5 T at RT compared to the H(A) = 0 for the non-nitrogenated materials. The Curie temperatures increase about 44% and the observed volume expansion is 3.6% for Mo and 2.8% for the V compound although the structure remains the same. A coercive field of 0.97 and 0.45 T has been observed at 4.2 K for NdFe10Mo2Nx and NdFe10V2Nx compounds, respectively.
