We have been working on fabricating Josephson junctions (JJs) by drawing a barrier layer on a thin film of a cuprate high-temperature superconductor YBa2Cu3O7-δ (YBCO) using a focused helium ion beam. In this study, we fabricated a YBCO dc-SQUID with that technique and measured the dependence of electrical properties on magnetic fields.
