摘要：

Exact analytical expression for the time-dependent magnetization of the system with known energy barrier distribution is obtained. The relation between the obtained result and usual definition of the magnetic viscosity is discussed. Corrections to the 'critical volume approach' are shown to be of order sigma(DELTA-E)/T, where sigma(DELTA-E) is the width of the energy barrier distribution density.
