摘要：

The magnetic viscosity of Sm2Fe17Nx (x = 1.6-3.5) with different particle sizes was measured with a vibrating sample magnetometer at 10-373 K and during a period of t = 6-1000 s. The magnetic viscosity parameter S-v was found to vary with the nitrogen concentration, showing a maximum value at x = 3.0. The relationship between log(S-v) and log(H-c) fits the Barbier linear plot fairly well, with a slope of about 0.9. The activation volume V of Sm2Fe17Nx decreases as the nitrogen concentration increases. The value of V can be related to the H-c value by H-c = V--n (n = 1.0-1.4).
