A pronounced resonance-like structure has been observed in the current dependence of AC susceptibility for two-dimensional array of unshunted Nb-AlOx-Nb Josephson junctions. Using a single-plaquette approximation, we were able to successfully fit our data assuming that resonance structure is related to the geometric (inductive) properties of the array.

    ABSTRACT: In this paper, we report on different phenomena related to the magnetic properties of artificially prepared highly ordered (periodic) two-dimensional Josephson junction arrays (2D-JJA) of both shunted and unshunted Nb-AlOx-Nb tunnel junctions. By employing mutual-inductance measurements and using a high-sensitive bridge, we have thoroughly investigated (both experimentally and theoretically) the temperature and magnetic field dependence of complex AC susceptibility of 2D-JJA. We also demonstrate the use of the scanning SQUID microscope for imaging the local flux distribution within our unshunted arrays.

    ABSTRACT: Results on the temperature and magnetic field dependence of current-voltage characteristics (CVC) are presented for SNS-type 2D ordered array of Nb-Cu0.95Al0.05-Nb junctions. The critical current I-C(T, H) and the power exponent a(T, H) = 1 + phi I-0(C)(T, H)/2k(B)T of the nonlinear CVC law V = R[I-I-C(T,H)](a(T,H)) are found to have a maximum at non-zero value of applied magnetic field H-p = 225 Oe, which is attributed to manifestation of pi-type Josephson contacts in our sample.

    ABSTRACT: We present recent results on the magnetic field dependence of currentvoltage characteristics (CVC) for an artificially prepared two-dimensional array of unshunted NbAlOxNb Josephson junctions. The results obtained from the measured CVC and critical current IC(T,H) differential magnetoresistance (DMR) R(T,H)=[dVdI]I=IC(T,H) of the array are found to exhibit behavior compatible with field induced KosterlitzThouless transition describing unbinding of vortexantivortex pairs under applied magnetic field. © 2011 Elsevier Ltd.
