Physical review letters, 2002•APSPhase transitions create a domain structure with defects, which has been argued by Zurek
and Kibble (ZK) to depend in a characteristic way on the quench rate. We present an
experiment to measure the ZK scaling exponent σ. Using long symmetric Josephson tunnel
junctions, for which the predicted index is σ= 0.25, we find σ= 0.27±0.05. Further, we agree
with the ZK prediction for the overall normalization.
