Abstract
We have studied the influence of the piezoelectric properties of the PMN-PT substrate ([Pb(Mg1/3Nb2/3)O3]1-x – [PbTiO3]x where x = 0.29 − 0.31) on the properties of the superconducting spin valve Fe/Al/Co/Pb exposed to electric and magnetic fields. According to the research results, with an increase in the applied electric field to the PMN-PT substrate, it is possible to register an increase in the shift of the superconducting transition temperature of the superconducting spin valve Fe/Al/Co/Pb. The maximum shift was 36 mK when an electric field of 1 kV/cm was applied, which was half of the superconducting transition width. The shift of the superconducting transition temperature equal to 255 mK in a magnetic field was recorded, and thus the possibility of a full superconducting spin valve effect was shown.
