Garreis, Rebekka 2018-10-18T12:55:35Z Leiderer, Paul Shaulov, Avner Strigl, Florian Espy, Christopher We study the magnetoresistance of aluminium 'double-networks' formed by connecting the vertexes of nano-loops with relatively long wires, creating two interlaced subnetworks of small and large loops (SL and LL, respectively). Far below the critical temperature, Aharonov-Bohm like quantum interference effects are observed for both the LL and the SL subnetworks. When approaching T <sub>c</sub>, both exhibit the usual Little-Parks oscillations, with periodicity of the superconducting flux quantum Φ <sub>0</sub> =h/2e. For one sample, with a relatively large coherence length, ξ, at temperatures very close to T <sub>c</sub>, the Φ <sub>0</sub> periodicity of the SL disappears, and the waveform of the first period is consistent with that predicted recently for loops with a size a < ξ, indicating a crossover to 2Φ <sub>0</sub> periodicity. terms-of-use Garreis, Rebekka Scheer, Elke Leiderer, Paul Espy, Christopher Yeshurun, Yosef 2018-04-19 eng Strigl, Florian Sharon, Omri J.
