摘要
A method is proposed to determine the dynamical critical exponent. The method is based on the scaling for dynamical hysteresis resulted from a linearly swept field. We prove that in model A dynamical hysteresis scaling at critical temperature is universal. The nearest-neighbor Ising models are used to demonstrate:such concepts and the dynamical critical exponents can be determined accurately. We also propose a universal relation between static and dynamical critical exponents in Ising class in single-spin-flip dynamics.
