摘要

摘要作者研究了 PMN-PT（[Pb(Mg1/3Nb2/3)O3]0.7-[PbTiO3]0.3）压电衬底对 Co1/Cu/Co2/Cu/Pb 薄膜异质结构超导特性的影响。检测到超导转变温度 Tc 在电场和磁场中的变化。在 1 kV/cm 的外加电场中，Tc 值之间的最大差异为 15 mK。在外部磁场中，当铁磁层磁化的相互方向从平行变为垂直时，最大的 Tc 差值超过 80 mK。

Superconducting Properties of a Co1/Cu/Co2/Cu/Pb Heterostructure on a PMN‒PT Piezoelectric Substrate

The authors study the effect a PMN‒PT ([Pb(Mg_1/3Nb_2/3)O₃]_0.7‒[PbTiO₃]_0.3) piezoelectric substrate has on the superconducting properties of a Co1/Cu/Co2/Cu/Pb thin-film heterostructure. A change in temperature T_c of the superconducting transition in electric and magnetic fields is detected. The maximum difference between T_c values is found to be 15 mK in an applied electric field of 1 kV/cm. In an external magnetic field, the greatest T_c difference is more than 80 mK upon changing the mutual orientation of the magnetizations of ferromagnetic layers from collinear to perpendicular.
