The value of the dynamic critical exponent {ital z} is studied for two-dimensional superconducting, superfluid, and Josephson junction array systems in zero magnetic field via the Fisher-Fisher-Huse dynamic scaling. We find z{approx_equal}5.6{plus_mi

Zero-field current–voltage ( I–V ) characteristics of a thin (`two-dimensional') Bi 2 Sr 2 CaCu 2 O 8+ δ crystal are reported and analyzed in two ways. The `conventional' approach yields ambiguous results while the dynamical scaling analysis of

We present evidence for nonequilibrium two stage melting in Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}}. Samples cooled in low applied magnetic fields display a sharp hysteretic drop of the resistance which is associated with a first-order vortex l

The flux transformer geometry has been useful for studying vortex coupling in Bi2Sr2CaCu2O8+y crystals but is limited by the difficulty of controlling sample size. We have used an argon ion mill to etch two channels into the top face of a Bi2Sr2CaCu2

We find that resistive hysteresis accompanies vortex lattice melting in Bi2Sr2CaCu2O8+° single crystals, together with a sharp drop of the resistance with decreasing temperature. The melting transition temperatureT m was current dependent, indicatin
