Abstract
We consider the critical current as a function of the applied magnetic fiel d for Josephson junctions. In paipticular we show that broken time reversal symmetry in the short junction limit for general junctions and self-fields in 0-pi junctions both give rise to an asymmetry in the critical current a s the magnetic field is reversed. Varying the junction size can distinguish between these two sources of asymmetry. (C) 1998 Elsevier Science Ltd. All rights reserved.
