A persistent current switch (PCS) is used for various superconducting applications, such as superconducting magnetic energy storage (SMES) system. The authors have proposed a mechanical switch of Y–Ba–Cu–O (YBCO) bulk as a PCS. In previous stud

We have developed a low-cost, short time manufacturing process using a novel method, starting from a mixture of Er2BaO4, BaCuO2, and CuO, with an excess of Er at expense of Ba. Several micrometers thick films were prepared by the screen-printing tech
