The last two decades demonstrated intensive study of layered superconductor-ferromagnet (S/F) nanostructures motivated by their implementation in superconducting spintronics. The theory of S/F hybrid heterostructures with two and more ferromagnetic layers predicts the generation of nonuniform superconductivity, a long-range odd-in-frequency triplet pairing at non-collinear alignment (NCA) of the F-layers magnetizations. Using the ideas of the superconducting triplet spin-valve we have fabricated functional nanostructures Co/CoOx/Cu41Ni59/Nb/ were triplet pairing with switching from normal to superconducting state takes place. The resistance of the samples as a function of an external magnetic field shows that the system is superconducting at the collinear alignment of the Cu41Ni59 and Co layers magnetic moments, but switches to the normal conducting state at the NCA configuration. Upon cycling the in-plane magnetic field in the range and keeping temperature close to the superconducting transition, a memory effect has been detected, The fabricated S/F functional nanostructures can serve as the rapid operating switching element of superconducting electronics and memory element MRAM for novel computers generation. The study was financially supported by the Russian Science Foundation Grant ( RSF ) Nr. 20-62-47009 “Physical and engineering basis of computers non-von Neumann architecture based on superconducting spintronics”.
