摘要：

We report measurements of the dependence on magnetic field and array size of the resistive transition of Josephson junction arrays with long-range interaction. Because every wire in these arrays has a large number of nearest neighbors (9 or 18 in our case), a mean-field theory should provide an excellent description of this system. Our data agree well with this mean-field calculation, which predicts that T-c (the temperature below which the array exhibits macroscopic phase coherence) shows very strong commensurability effects and scales with array size.
