Abstract
A four terminal Josephson device, based on quasiparticle injection into an YBCO step edge Josephson junction was analysed. Two injector junctions are defined on both sides of the step edge junction using native Au/YBCO barrie r. The Josephson critical current is reduced by increasing the injection cu rrent. The results are explained in terms of a non equilibrium state of the YBCO electrode under quasiparticle injection.
