Method for reliable realization of a varphi Josephson junction
N. G. Pugach, E. Goldobin, R. Kleiner +1
We propose a method to realize a Josephson junction by combining alternating 0 and parts (sub junctions) with an intrinsically non-sinusoidal current-phase relation (CPR).…
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…
Magnetic interference patterns in 0-Pi SIFS Josephson junctions: effects of asymmetry between 0 and Pi regions
M. Kemmler, M. Weides, M. Weiler +8
We present a detailed analysis of the dependence of the critical current I_c on the magnetic field B of 0, Pi, and 0-Pi superconductor-insulator-ferromagnet-superconductor Josephso…
Imaging of order parameter induced phase shifts in cuprate superconductors by low-temperature scanning electron microscopy
Christian Gürlich, Edward Goldobin, Rainer Straub +6
Low-temperature scanning electron microscopy (LTSEM) has been used to image the supercurrent distribution in ramp-type Josephson junctions between Nb and either the electron-doped…
Cold atoms near superconductors: Atomic spin coherence beyond the Johnson noise limit
B. Kasch, H. Hattermann, D. Cano +6
We report on the measurement of atomic spin coherence near the surface of a superconducting niobium wire. As compared to normal conducting metal surfaces, the atomic spin coherence…
Thermal escape of fractional vortices in long Josephson junctions
U. Kienzle, T. Gaber, K. Buckenmaier +5
We consider a fractional Josephson vortex in a long 0-kappa Josephson junction. A uniformly applied bias current exerts a Lorentz force on the vortex. If the bias current exceeds t…
