'Inverse' melting of a vortex lattice
Article Abstract:
Research is presented describing first-order inverse melting of the vortex lattice in a high-temperature superconductor. When a crystal's temperature is reduced, and the crystal reversibly transforms into an amorphous or liquid phase, this is known as inverse melting.

Transport properties governed by surface barriers in Bi2Sr2CaCu2O8
Article Abstract:
In crystals of the anisotropic high-temperature superconductor Bi2Sr2CaCu2O8, most of the current flows at the edges of the sample, instead of in the bulk, even in the very resistive state. This is attributable to the presence of strong surface barriers. These findings have significant implications for the interpretation of transport measurements, as the total measured resistance is that of the surface barrier, rather than that of the bulk.
