چکیده

We report on vortex transport in Bi2Sr2Ca1−xYxCu2O8 crystals irradiated at different doses of heavy ions. We show evidence of a flux-creep resistivity typical of a variable-range vortex hopping mechanism as predicted by Nelson and Vinokur.

Localized Flux Lines and the Bose Glass

Columnar defects provide effective pinning centers for magnetic flux lines in high–Tc superconductors. Utilizing a mapping of the statistical mechanics of directed lines to the quantum mechanics of two–dimensional bosons, one expects an entangled flux liquid phase at high temperatures, separated by a second–order localization transition from a low–temperature “Bose glass” phase with infinite ti...

Low-temperature magnetic relaxation in HgBa2Ca2Cu3O81d single crystals with columnar defects

Micrometer-sized Hall probes are used to measure the low-temperature magnetic properties of HgBa2Ca2Cu3O81d single crystals with and without columnar defects. Introduction of columnar defects by heavy-ion irradiation suppresses the quasiexponential temperature dependence of the critical current, but only when the density of flux lines is less than the density of defects. The current-dependent c...

Bose glass melting and the transverse Meissner effect in YBa2Cu3O7Àd single crystals

We map out the phase boundary separating the vortex solid and liquid phases in YBa2Cu3O72d ~YBCO! single crystals with irradiation-induced columnar defects. These randomly distributed, extended defects are expected to localize vortices into a ‘‘Bose glass’’ phase. The transition from the vortex liquid into the Bose glass is predicted to exhibit two fundamental signatures: a vanishing of the lin...

Vortex flow and transverse flux screening at the bose glass transition

We study the vortex phase diagram in untwinned YBCO crystals with columnar defects. These randomly distributed defects are expected to induce a "Bose glass" phase of localized vortices exhibiting a vanishing resistance and Meissner effect for magnetic fields H( perpendicular) transverse to the columns. We directly observe the transverse Meissner effect using a Hall probe array. As predicted, th...

Hopping Conductivity in Single Crystals (Cd0.6Zn0.32Mn0.08)3As2 (RESEARCH NOTE)

The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this w...
