- Аннотация: The critical current I(C) of S-FNF-S Josephson junctions, which are ferromagnet (F)-normal metal (N)-ferromagnet multilayer structures whose ends are in contact with the superconducting (S) electrodes, has been calculated. It has been shown that both the magnitude and sign of I(C) depends significantly on the misorientation angle alpha of the magnetization vectors M(1,2) of the ferromagnetic films and the distance L between the superconducting electrodes. The effect of the triplet superconducting component similar to[psi up arrow psi up arrow] similar to [psi down arrow psi down arrow] appearing in the structure on I(C)(alpha) has been analyzed. It has been proven that a new type of the pi junction exists, appearing due to the superposition of two contributions to I(C) that decrease monotonically with L and are damped at lengths about the coherence length of the normal metal. It has been shown that the effective control over the magnitude and sign of I(C) of the structure is achieved at a small deflection of the vectors M(1,2) from the antiferromagnetic (M(1) up down arrow M(2)) configuration.
