For the improvement of superconducting properties of BaMO3 (M=Zr, Sn, HQ-doped REBa2Cu3Oy films, we focused on the Tc reduction caused by lattice misfit between BaMO3 and REBa2Cu3Oy. We compared the influence on the Tc reduction of BaZrO3, BaSnO3 and BaHfO3-doped SmBa2Cu3Or (SmBCO) films with various BMO contents. From the correlation between configuration of nanorods and c-axis expansion, it was suggested that the lattice strain working on the SmBCO matrix became stronger in the order of BaHfO3, BaZrO3 and BaSnO3. Therefore, the combination of SmBCO and BaHfO3 is better regarding the suppression of the Tc reduction compared with other combinations of SmBCO and BaMO3.
