The superconducting properties of niobium-titanium alloy multilayers.

摘要

We fabricated and measured thin film NbFor applied fields near parallel with the layers, the upper critical fields showed quasi-two dimensional behavior associated with the well-known 3D-to-2D dimensional crossover of the superconducting order parameter. At these same angles, the critical current densities of many of the multilayers showed strong peak effects versus field in the range 0.2-0.5
