Increasing the critical current density (J_c) in a magnetic field is an important goal for improving the performance and lowering the cost of superconducting wires. Previous studies have reported that the J_c in magnetic field is improved by mixing two types of REBCO thin films. Therefore, in this study, we fabricated five kinds of REBCO (RE=Yb, Tm, Er, Ho, Dy) mixed films by the Nd:YAG-PLD method and evaluated their composition and superconducting properties. We also attempted to optimize the superconducting properties of REBCO thin films using Bayesian optimization.
