Abstract

Irreversibility lines and distributions of local critical current density (Jcl) based on the percolation transition model were affected by the growth temperature (Ts) in 3.5 wt.%-BaNb2O 6-doped ErBa2Cu3Oy thin films. The vortex-Bose-glass-like state appeared by the introduction of nano-rods, and this vortex state was affected by Ts. The shape and width of the J cl distribution strongly depended on Ts. These results are probably caused by variations of the density and the growth direction for nano-rods reflecting Ts. The growth temperature is an important factor to achieve higher critical current properties under magnetic fields for coated conductors of rare-earth-based cuprates with nano-rods.
