| Research Abstract |
We studied the magnetic effects of magnetic nanoparticle (NP) patterns inserted into superconducting devices to develop superconductor-spin hybrid devices, which enhance the performance of superconducting circuits and add new functionality to the circuits. W e found that NP film patterns with high permeability, or residual magnetization were obtained using NPs with appropriate particle size. We also developed fabrication processes of high-uniformity NbN Josephson junctions and high-temperature superconductor devices for producing nanoSQUIDs.
