✦ Synopsis

The Ising-like phase transitions in square lattice fully frustrated (FF) XY models are studied using the short-time Monte Carlo method for two realizations: (A) Ferromagnetic and antiferromagnetic couplings arranged in a zigzag pattern and (B) they arranged in an alternate columns pattern. We find that the critical exponent v is dependent on the definition of order parameters: the staggered chiral magnetization Mx and the staggered magnetization M,,. For both kinds of FFXY models, they have almost the same short-time behavior with critical exponent v < I.
