Abstract
We have proposed a fabrication process of intrinsic Josephson junction s (IJJs) using AFM lithography and successfully obtained IJJs in YBaCu O thin films deposited by MOCVD. A sample shows clear hysteresis and 2 3 voltage steps related to IJJs in the I-V curve. The maximum width of a step is about 2 mV at 5 K. We discuss the I-V characteristics and e stimate the order of the parameters for the IJJ. (C) 1997 Elsevier Sci ence B.V.
