Second-harmonic current-phase relation in Josephson junctions with ferromagnetic barriers
M. J. A. Stoutimore, A. N. Rossolenko, V. V. Bolginov +7
We report the observation of a current-phase relation dominated by the second Josephson harmonic in superconductor-ferromagnet-superconductor junctions. The exotic current-phase re…
Fabrication and measurements of hybrid Nb/Al Josephson junctions and flux qubits with pi-shifters
A. V. Shcherbakova, K. G. Fedorov, K. V. Shulga +8
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 employi…
Implementation of superconductor-ferromagnet-superconductor pi-shifters in superconducting digital and quantum circuits
A. K. Feofanov, V. A. Oboznov, V. V. Bol'ginov +10
The difference between the phases of superconducting order parameter plays in superconducting circuits the role similar to that played by the electrostatic potential difference req…
Vortex states in mesoscopic superconducting squares: Formation of vortex shells
H. J. Zhao, V. R. Misko, F. M. Peeters +3
We analyze theoretically and experimentally vortex configurations in mesoscopic superconducting squares. Our theoretical approach is based on the analytical solution of the London…
Observation of the magnetic domain structures in CuNi thin films at low temperatures
I. S. Veshchunov, V. A. Oboznov, A. N. Rossolenko +4
We report on the first experimental visualization of domain structure in films of weakly ferromagnetic CuNi alloy with different thickness at liquid helium temper…
Imaging spontaneous currents in superconducting arrays of pi-junctions
Sergey M. Frolov, Micah J. A. Stoutimore, Trevis A. Crane +6
Superconductors separated by a thin tunneling barrier exhibit the Josephson effect that allows charge transport at zero voltage, typically with no phase shift between the supercond…
