摘要：

Weak links were fabricated by pulsed laser deposition of YBa2Cu3O(x) thin films on Y-ZrO2 bicrystal substrates. They were formed by transferring the bicrystal boundary into the epitaxial film during the film growth. Their properties were determined by the misorientation angle (theta) between the two halves of the bicrystal. The transport properties of the weak links were studied as a function of theta and an exponential dependence of the weak link critical current density was observed for angles up to 45-degrees. Clear Josephson effects with good microwave and magnetic field response were observed.
