| Research Abstract |
In this work, an improvement of in-field critical current density J_c in high-T_c superconducting thin films were attempted by multilayering with sandwich structure which consisted of non-doped superconducting YBCO layers and BaZrO_3-doped YBCO layers. We clarified that by controlling the YBCO layer thickness and the growth temperature, the distribution of the BaZrO_3 nano-particles and the angular dependence of J_c in BaZrO_3/YBCO multilayered films varied in a controlled way.
