A simple economical conventional vacuum system was used for evaporation of YBCO thin films on as‐deposited unbuffered Ag layers on MgO substrates. The subsequent heat treatment was carried out in low oxygen partial pressure at a relative low temperature and short dwelling time. The films thus obtained were characterized for electrical properties using dc four‐probe electrical measurements and inspected for structural properties and chemical composition by scanning electron microscopy (SEM).
