Abstract :
We have investigated PAT (Photon-Assisted-Tunneling) effect induced by SMMW (Submillimeter-Wave) in SIS point-contacts with an insulating barrier containing magnetic impurities: a magnetic barrier. The junctions turned out to have severely suppressed dc and ac Josephson currents, which makes them promising junctions for a high frequency mixer using PAT effect.
