抄録

We prepared various MgO substrates cut from various ingots with different impurity-Ca concentrations and deposited NdBa₂Cu₃O _7-δ (NBCO) thin-films on them by using molecular beam epitaxy (MBE). As a result, we found that the room temperature resistivity (ρ_(RT)) of NBCO thin-films and the Ca concentration in an MgO substrate are quantitatively correlated. Moreover we clarified the permissible impurity-Ca concentration in MgO substrates in terms of practical microwave applications.
