抄録

We have obtained a REBa₂Cu₃O_7-y (RE=rare earth element) superconducting single-crystal thin film on a MgO (100) substrate using a magnetron sputtering method. For a HoBa₂Cu₃O_7-y thin film, we obtained a J_c of more than 3×10⁶A/cm² at the temperature of liquid nitrogen, and the deterioration of the magnetic field was far less than that for sintered bulk material. Through X-ray diffraction, it was confirmed that the growth of the c axis was perpendicular to the substrate. In addition, reflection high energy electron diffraction and observation with a high resolution scanning electron microscope confirmed that the surface was extremely smooth and flat. This is a great improvement in comparison with the poly-crystal film (with a J_c of 10⁴ to 10⁵A/cm²) which was previously reported, and it is expected that this can open the way for applications in electronics fields which require a J_c of 10⁶A/cm² or higher.
