Abstract

We report the effect of BaHfO₃ (BHO) introduction into SmBa₂Cu₃O_y (SmBCO) films on the transport properties at artificial grain boundaries (AGBs) by comparing pure SmBCO and BHO-doped SmBCO films deposited on bicrystal substrates. Improvement of the critical current density (J_c) at the AGB of BHO-doped SmBCO films was con firmed under the magnetic fields at which J_c was restricted at the AGB. By investigating the superconducting properties and from TEM observations, we found that the in-field J_c value for BHO-doped SmBCO films was improved through flux pinning of the Abrikosov-Josephson vortices by BHO nanorods.
