Abstract

We present our study of the vortex solid-liquid phase transition of superconducting Bi2Sr2Ca2Cu3O10 in the mixed state, based on our detailed transport measurements of a Bi2Sr2Ca2Cu3O10/Ag tape (Jc ≃ 2× l04 A/cm2 at 77 K and zero field) immersed in liquid neon (27K) and in liquid oxygen (54K - 90K) as a function of applied magnetic field up to 17 T. A comprehensive vortex phase diagram is obtained. We show that the vortex solid-liquid transition is the fundamental limiting factor for Jcin this tape at T ≥ 27 K in magnetic field (except at very low field). In addition, the field-dependence of the flux pinning force in both solid and liquid regime is discussed.
