Abstract

BaSnO3 (BSO)-doped ErBa2Cu3O7-δ (ErBCO) films are grown by a pulsed laser deposition (PLD) method on SrTiO3 (STO) substrates for realizing high JC in a magnetic field. ErBCO ceramics with BSO-contents of 0-8.0 wt% are used as targets. From XRD analyses of the obtained films, 0 0 l reflections of ErBCO are observed, indicating that the films are c-axis oriented. BSO grew in a shape of nanorod in all ErBCO films. The BSO-doped ErBCO films showed higher JC than non-doped ErBCO films in magnetic fields, suggesting that BSO nanorods plays a role of pinning centers. On the other hand, the JC properties depended strongly on the concentration of BSO-doped in ErBCO films; a 4 wt% BSO-doped ErBCO film showed lower JC than that of a 2 wt% BSO-doped film. These BSO-content dependences on JC for ErBCO films were understood as poor alignment of ErBCO crystal grains caused by BSO doping. We believe that the optimized BSO doping content into ErBCO films for high JC is around 2 wt% among the obtained films.
