| Popis: | We have studied experimentally critical behaviors of vortex-lattice-melting transitions in a square Josephson junction array with quenched bond disorder, with a focus on frustrations f=1/2, 2/5, 1/3, and 1/5. Critical scaling analyses of the current–voltage characteristics show that quenched disorder may drive the transitions continuous but not to the Ising universality class. This finding is contrary to what observed in Monte Carlo simulations. |
