Josephson Effect in SFXSF Junctions
We investigate the Josephson effect in SFXSF junctions, where SF is a superconducting material with a ferromagnetic exchange field, and X is a weak link. The critical current Ic increases with the (antiparallel) exchange fields, if the distribution of transmission eigenvalues of the X layer has its maximum weight at small values. This exchange-field enhancement of the supercurrent does not exis...
متن کاملTheory of the Josephson effect in superconductor / ferromagnet / superconductor junctions
To reveal the influence of the exchange interaction on the Josephson effect, the d.c. Josephson current in unconventional-superconductor / ferromagnet / unconventional-superconductor junctions is studied. When the two superconductors have d-wave symmetry, the Josephson current is drastically suppressed with the increase of the exchange interaction. On the other hand, when the two superconductor...
متن کاملKinky Behavior in Josephson Junctions
We analyze nonperturbatively the behavior of a Josephson junction in which two BCS superconductors are coupled through an Anderson impurity. We recover earlier perturbative results which found that a δ = π phase difference is preferred when the impurity is singly occupied and the on-site Coulomb interaction is large. We find a novel intermediate phase in which one of δ = 0 and δ = π is stable w...
متن کامل3He Josephson Junctions
The flow of superfluid 3He-B through a 65 3 65 array of nanometer-size apertures has been measured recently by Backhaus et al. They find in the current-phase relation a new branch, the so-called p state. We study two limiting cases which show that the p state arises from the coupling of the phase degree of freedom to the spin-orbit rotation. The p state exists in a single large aperture, but is...
متن کاملJosephson effect in small - area superconducting tunnel junctions at 604
We have measured the ac Josephson effect in small-area superconducting tunnel junctions at 604 GHz (A = 496pm) using a resonant planar dipole antenna to couple the radiation into the junction. In a 176-fl junction, we have observed up to the 7th Josephson step (at 8.75 m V), a performance comparable to that seen in point contacts. We also compare our data with the results of the RSJ model and o...
