REBCO coated conductors (CCs) are expected to show high performance for superconducting applications due to their high tensile strength and high critical current density under magnetic fields. Fujikura Ltd. (Fujikura) has developed REBCO CCs with high performance by ion beam assisted deposition (IBAD) and pulsed laser deposition (PLD) method. It is generally known that the critical current (I-c) of a common superconducting wire varies with the applied longitudinal tensile strain, but that of Fujikura's commercial CC hardly varies due to the peculiarities of the REBCO crystal orientation. Recently, we have developed BaMO3 (BMO, M : Zr or Hf) doped REBCO CCs in order to enhance their in-field critical current density. In this study, we investigated the strain dependence of the BMO doped REBCO CCs. As a result, it was confirmed that the I-c change with strain increased by BMO doping, even though the crystal orientation did not change.
