摘要	The quasilogarithmic magnetic viscosity of the perpendicularly anisotropic Nd-Fe-B films is determined by measuring the time dependent magnetization in coercive fields at 300 K-4.2 K. The distribution of energy barrier heights in the films is believed to be the origin of this stretched exponential magnetic relaxation. Another feature exhibited in the anisotropic Nd-Fe-B films is the nonmonotonic temperature dependence of the magnetic viscosity coefficients, which are extracted by the decay slopes of the linear quasilogarithmic magnetic aftereffect curves.
