The focus of the present report is the comparison of pinning properties between a Bi 1.8 Pb 0.2 Sr 2 CaCu 2 O 8+d single crystal irradiated at 45 and the one irradiated along c-axis. At temperatures TX40 K, and in the vortex solid state, angular measurements reveal for both samples a pronounced dip
The first order melting transition (FOT) in vortex matter of clean Bi 2 Sr 2 CaCu 2 O 8 crystals, is identified by a discontinuity in the reversible magnetization, which extends to the low temperature (irreversible) regime in the form of a jump in the energy barrier vs. current, UรฐJ ร, variation.
