Josephson effect in mesoscopic graphene strips with finite width
Ali G. Moghaddam, Malek Zareyan
We study Josephson effect in a ballistic graphene strip of length smaller than the superconducting coherence length and arbitrary width . We find that the dependence of the…
Magneto shot noise in noncollinear diffusive spin-valves
B. Abdollahipour, M. Zareyan
We develop a semiclassical Boltzmann-Langevin theory of the spin polarized shot noise in a diffusive normal metal spin-valve connected by tunnel contacts to ferromagnetic reservoir…
Enhanced superconducting proximity effect in clean ferromagnetic domain structures
M. A. Maleki, M. Zareyan
We investigate the superconducting proximity effect in a clean magnetic structure consisting of two ferromagnetic layered domains with antiparallel magnetizations in contact with a…
Nonsinusoidal current-phase relations and the transition in diffusive ferromagnetic Josephson junctions
G. Mohammadkhani, M. Zareyan
We study the effect of the interfacial transparency on the Josephson current in a diffusive ferromagnetic contact between two superconductors. In contrast to the cases of the fully…
Shot noise in diffusive ferromagnetic metals
M. Hatami, M. Zareyan
We show that shot noise in a diffusive ferromagnetic wire connected by tunnel contacts to two ferromagnetic electrodes can probe the intrinsic density of states and the extrinsic i…
