Experimental evidence of a ϕ Josephson junction
H. Sickinger, A. Lipman, M. Weides +5
We demonstrate experimentally the existence of Josephson junctions having a doubly degenerate ground state with an average Josephson phase ψ=\pmϕ. The value of ϕ can be chosen by d…
Critical current diffraction pattern of SIFS Josephson junctions with step-like F-layer
M. Weides, U. Peralagu, H. Kohlstedt +6
We present the latest generation of superconductor-insulator-ferromagnet-superconductor Josephson tunnel junctions with a step-like thickness of the ferromagnetic (F) layer. The F-…
Interference patterns of multifacet 20x(0-pi-) Josephson junctions with ferromagnetic barrier
S. Scharinger, C. Gürlich, R. G. Mints +5
We have realized multifacet Josephson junctions with periodically alternating critical current density (MJJs) using superconductor-insulator-ferromagnet-superconductor heterostruct…
Josephson supercurrent in Nb/InN-nanowire/Nb junctions
R. Frielinghaus, I. E. Batov, M. Weides +3
We experimentally studied the Josephson supercurrent in Nb/InN-nanowire/Nb junctions. Large critical currents up to 5.7 A have been achieved, which proves the good coupling of t…
Visualizing supercurrents in ferromagnetic Josephson junctions with various arrangements of 0 and πsegments
C. Gürlich, S. Scharinger, M. Weides +5
Josephson junctions with ferromagnetic barrier can have positive or negative critical current depending on the thickness of the ferromagnetic layer. Accordingly, the Josephso…
High quality ferromagnetic 0 and pi Josephson tunnel junctions
M. Weides, M. Kemmler, H. Kohlstedt +4
We fabricated high quality $\Nb/\Al_2Ø_3/\Ni_{0.6}\Cu_{0.4}/\Nb$ superconductor-insulator-ferromagnet-superconductor Josephson tunnel junctions. Depending on the thickness of the f…
