The term "dynamic scaling" as one of the essential concepts to describe the dynamics of critical phenomena seems to originate in the seminal paper of Pierre Hohenberg and Bertrand Halperin (1977), namely they suggested "[...] that the wave vector- and frequency dependent susceptibility of a ferromagnet near its Curie point may be expressed as a function independent of | T − − T C | provided that the length and frequency scales, as well as the magnetization and magnetic field, are rescaled by appropriate powers of | T − − T C | .
