Vortex pinning/dynamics in YBCO films with Jc (77 K) > 3·106 A/cm2 studied by direct transport measurements

Description

Critical current density, Jc, is studied for highly biaxially-oriented YBCO thin films with Jc(77 K) > 3 MA/cm2 in a range of magnetic fields, temperatures, angles between magnetic field vector and film c-axis. Jc(H,θ) is shown to be dominated by vortex interaction with high density (>1011 lines/cm2) of linear pins--edge dislocations. A model is developed to describe different vortex arrays behavior in the presence of two-dimensional square network of linear pins
