Local density of states in superconductor-strong ferromagnet structures
F. S. Bergeret, A. F. Volkov, K. B. Efetov
We study the dependence of the local density of states (LDOS) on coordinates for a superconductor-ferromagnet (S/F) bilayer and a S/F/S structure assuming that the exchange energy…
Josephson current in superconductor-ferromagnet structures with a nonhomogeneous magnetization
F. S. Bergeret, A. F. Volkov, K. B. Efetov
We calculate the dc Josephson current for two types of superconductor-ferromagnet (S/F) Josephson junctions. The junction of the first type is a S/F/S junction. On the basis…
Enhancement of the Josephson current by an exchange field in superconductor-ferromagnet structures
F. S. Bergeret, A. F. Volkov, K. B. Efetov
We calculate the dc Josephson current for two superconductor-ferromagnet (S/F) bilayers separated by a thin insulating film. It is demonstrated that the critical Josephson current…
