Critical Dependencies in Three-Layered Josephson Junctions

Cover Page

Abstract


Sakai-Bodin-Pedersen model is used to investigate numerically the dynamics of the Josephson phases in three stacked long Josephson Junctions. It is shown that the critical currents of the individual junctions depend on the damping and the coupling parameters and that there is a domain in vicinity of zero magnetic field where the junctions switch to nonzero voltage simultaneously, i.e. current locking takes place.
