Abstract

We have performed detailed SANS investigations on a large, high quality, twinned YBCO single crystal. The crystal was oriented with H 51 degrees to c to reduce the effect of twin plane pinning. The diffracted intensity was found to disappear at a temperature well below H_c2(T). The data is consistent with a Lindemann melting criterion, giving a physically reasonable value for c_L of 0.15 that is in good agreement with previous work. The disappearance of the diffracted intensity coincides with the irreversibility line as measured by an inductance technique.
