Influence of layer thickness and growth temperature on in-field Jc in BaZrO3/YBa2Cu3Oy quasi-multilayered films

► BaZrO3-doped YBCO thin films were fabricated by a quasi-multilayering process. ► The thickness of a YBCO layer and the growth temperature were modulated. ► The Jc(θ) properties exhibited both random pinning and c-axis-correlated one. ► The peak of Jc around B||c emerges for films grown at higher temperature. ► The Jc peak developed and increased with decreasing thickness of a YBCO layer.
