Transition from columnar to point pinning in coated conductors: critical currents that are independent of magnetic field direction

We identify a sharp crossover in the vortex pinning of a high-temperature superconductor with nanocolumnar stacks of precipitates as strong vortex pinning centers. Above a particular, temperature-dependent field BX(T) the vortex response is no longer determined by the nanocolumns, and is instead det...
