Research Abstract

We have successfully fabricated Gd-system superconducting thin films with insulating nanoparticles of 3nm by a metal-organic deposition technique using metal-organic coating solutions which zirconium was chemically doped. The superconducting thin films with nanoparticles showed high critical density performance in magnetic fields. Furthermore, it was found that the MOD-superconducting thin films grown on the surface-decorated substrates with 3nm-highinsulating nanoislands indicate the critical density of over 1MA/cm~2 and improved critical density characteristic in magnetic fields above 1T.
