N2 - The influence of the matching field (BΦ) on critical current density (Jc) and irreversibility temperature (Tirr) in YBa2Cu3O7 films containing BaMO3 (M = Zr, Sn, Hf) nanorods was investigated. It was revealed that the irreversibility temperature normalized by the critical temperature (Tirr/Tc) was influenced by BΦ, for B > BΦ, but Tirr/Tc did not depend on which BaMO3 material was used for B < BΦ, i.e., there was no dependence on nanorod density, diameter, interface sharpness, or Tc in the case of ideal nanorods. However, Jc/Jc(0 T) was found to decrease with increasing BΦ at low magnetic field strengths and to improve at high magnetic field strengths. In addition to Jc being dependent on BΦ, the Tc term in Tirr and Jc(0 T) were also found to have an effect on Jc.
