N2 - BaMO3 (BMO, M: Zr or Hf)-doped REBCO-coated conductors were prepared by Hot-Wall PLD method on IBAD template. The highest Jc was obtained for BaHfO3-doped EuBCO. Quite strong pinning force density (Fp) of 1.6 TN/m3 was observed at 4.2 K, 15 T, for a sample deposited with growth rate of ∼5 nm/s. It had strong c-axis correlated pinning at the temperature above 20 K with the matching field of ∼5 T. A 45-m-long sample was formed by productive high growth rate over 20 nm/s, being consistent with commercial nondoped conductors. It had also large Ic of 1687 A/cm and Fp of 0.96 7 TN/m3 was obtained at 4.2 K, 15 T. The end-to-end longitudinal Ic homogeneity (σ) at 77 K in low field was evaluated to be 2.2% by magnetization. Transport in-fields Ic were also measured for the both end points at 30 K, 2 T, resulting in 1863 and 1883A/cm, respectively.
