Abstract
Simultaneous measurements of resistivity and local magnetization using microscopic Hall sensors were carried out on Bi2Sr2CaCu2O8 crystals a s a function of applied field and temperature. The resistivity onset i s found to occur concurrently with the first-order vortex-lattice phas e transition, determined by the equilibrium magnetization step. This b ehavior strongly suggests that the vortex lattice melts at the phase t ransition. The apparently reversible magnetization below the transitio n is ascribed to substantial flux creep.
