Abstract: The non-equilibrium phase transition, Ising-like phase transition of two-dimensional fully-frustrated Josephson junction arrays driven by external current was studied in the framework of the short-time dynamic scaling method. Within the resistively shunted junction (RSJ) dynamics, besides the critical temperature TC, the static critical exponents 2β/υ and υ, and dynamic critical exponent z were obtained.

Key words: Josephson junction arrays, Short-time dynamics, Ising-like phase transition
