Comment on ``Generalized Dynamic Scaling for Critical Relaxation" [Phys. Rev. Lett. 77, 679 (1996), cond-mat/9607013]
Abstract
Description
We point out that in nonequilibrium relaxational processes the magnetic field of the initial state (instead of the initial magnetization) has to be considered as the additional scaling field (related to the initial state). Taking this into account the interpretation of the scaling behavior observed in the paper by Zheng becomes more straightforward.
