We have implemented a trilayer technological approach to fabricate $$\mathrm {Nb}{-}\mathrm {Cu}_{0.47}\mathrm {Ni}_{0.53}{-} \mathrm {Nb}$$ superconducting phase inverters ( $$\pi $$ -junctions) with enhanced critical current. Within this technique,

We report the observation of a current-phase relation dominated by the second Josephson harmonic in superconductor-ferromagnet-superconductor junctions. The exotic current-phase relation is realized in the vicinity of a temperature-controlled 0-to-$\

The temperature-and magnetic-field dependences of the magnetic moment of square Josephson arrays with SIS-type junctions are studied experimentally. Two temperature regions are observed with different types of magnetization curves. Magnetic flux aval

Superconductor—ferromagnet—superconductor (SFS) π- junctions1 were investigated experimentally. The transitions to π-state and back to the conventional 0-state were found to result from temperature decrease or ferromagnetic interlayer thickness

Both experimental and numerical studies of a self-frustrated triangular array of π-junctions are reported. The array of SFS Josephson junctions shows a transition to the π-state and self-frustration with a decrease in temperature. This manifests it

Phase interference in arrays of superconductor-ferromagnet-superconductor (SFS) Josephson junctions has been investigated experimentally. A transition of the SFS junctions to the π-state manifests itself in the half-period shift of the external magn

The field dependence of the magnetic moment of square (100×100) SNS-type Josephson junction arrays was studied by a SQUID magnetometer. A considerable difference in the behavior of this dependence was revealed for the cases of the entry of magnetic

We describe fabrication and testing of composite flux qubits combining Nb- and Al-based superconducting circuit technology. This hybrid approach to making qubits allows for employing pi-phase shifters fabricated using well-established Nb-based techno

The field dependence of the magnetic moment of square (100×100) Josephson networks was examined with the use of a SQUID magnetometer. The field dependence of the magnetic moment was found to be regular with features corresponding to integer and half
