中文摘要	The time dependence of magnetization is usually expressed as M(t)=M-0-Slnt [see Proc. Phys. Soc. 62, 562 (1949)] for magnetic viscosity experiments. Considering magnetic interaction during the thermal activation process, a form as M(t)=M-0-Sln(t+t(0)) is deduced. The dipolar interaction and exchange coupling in a magnet can lead to positive and nonpositive t(0), respectively. In the experiments of the magnetic viscosity for nanocrystalline Pr2Fe14B ribbons, the existence of positive t(0) is confirmed.
