| Popis: | We have studied the superconducting spin-valve effect in a F1/F2/S heterostructure containing a Heusler alloy layer standing for an F2 layer. The Heusler alloy layer was grown at the substrate temperature T sub = 300 K . According to our previous data in such preparation conditions this layer is a weak ferromagnet. For the samples with the Heusler layer thickness d Heusler = 1 and 4 nm the full switching between the normal and superconducting states is realized with the dominant aid of the long-range triplet component of the superconducting pair condensate which occurs at the perpendicular mutual orientation of magnetizations. |
