Abstract

AC transport measurements show that the vortex dynamics in a twinned superconducting Y-Ba-Cu-O single crystal are consistant with a second order vortex-solid melting transition. Indentification of the universal functions and consistent measurements of the critical exponents v = 0.7 and z= 3.0 found in magnetic fields from IkOe to 90kOe as well as DC transport measurements offer strong evidence for this transition.
