Objetivo The objective is the fabrication and characterisation of devices designed to exhibit a new effect, which could widen the domain of applications of Josephson junctions in superconducting electronics (e.g. spectrometry): A "Josephson" behaviour is predicted in devices involving an array of Abrikosov vortices in a superconducting thin film and a periodic potential. "DC Josephson-like" (resp. "AC Josephson-like") effect corresponds to a constant position (resp. a drift) of the array in the potential. The DC effect has been observed by Giaever in a structure called DC Transformer (DCTr). Shapiro steps created by incident RF signal are predicted, appearing at voltages proportional to signal frequency (of the order of 1 mV/GHz). This ratio can be set by design, and tuned by a magnetic field, in contrast with the classical Josephson effect. In the DCTr, the periodic potential is obtained by magnetic coupling with an other array of vortices in a second superconducting thin film, but there is no restriction on the origin of this potential.Low TC multilayer structure and HTc homoepitaxial structures are evaluated in the first phase of the project, while HTc multilayer structures will be performed in the second phase.
