... trapping of magnetic quanta in an annular Josephson junction M. Aaroe(1), R. Monaco ... A long and narrow annular Josephson tunnel junction sandwiched between two ... al.(2000)[3] proposed testing in annular Josephson Tunneling Junctions AJTJs For ...
... The motivation for using long annular Josephson junctions is that - because of the annular geometry - any fluxons created during the quench, will be trapped in the junction until it is reheated, because of the Meissner effect of the superconducting annuli ...

... B. Annular junctions Further, we have measured the static properties of several Nb / Alox / Nb-Nb annular JTJs having the same critical current density Jc =60 A/cm2 J =50 m , the same width R =4 m, but different radius R ranging from 80 to 500 m. The ...
... annular Josephson tunnel junctions in the presence of a magnetic field R. Monaco* Istituto di Cibernetica del C.N.R., 80078 Pozzuoli, Italy and Unita' INFM-Dipartimento di Fisica, Universita' di Salerno, 84081 Baronissi, Italy M. Aaroe and J. Mygind ...
... The static properties of an annular junction in a transverse field have been numerically investigated in Ref. 9 for a Lyngby-type annular JTJ obtained by two films having the same widths;24 it was found that in a first approximation, Hr sinusoidally ...
... Fig. 11. A comparison of three different shapes of the FSS motif a ring, an annular square and an annular hexagon. ... Three shapes were chosen--a ring, an annular square described earlier and an annular hexagon. ...
... The cut leaves a gapped annular junction and relieves the junction from the constraint of the 2 -periodic boundary condition of annular junctions.5 In that experiment the ring itself acted as the junction base electrode while the top electrode had the ...
