Anomalous superconducting properties at magic doping levels in under-doped La2-xSrxCuO4 single crystals

F. Zhou, P. H. Hor, X. L. Dong +3

A series of high-quality under-doped La2-xSrxCuO4 superconductor crystals with x = 0.063 - 0.125 were prepared by traveling-solvent floating-zone (TSFZ) technique. We found by dc m…

Absence of a True Vortex-Glass Phase above the Bragg Glass Transition Line in Bi-2212

S. L. Li, H. H. Wen

In magnetic measurements on Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ (Bi-2212) single crystals, a general peak with a dynamical feature on both $S - H$ and $S - T$ curves was found with S the mag…
