Control of Both Superconducting Critical Temperature and Critical Current by Means of Electric-Field-Induced Reconfigurable Strain

Journal Article


Abstract


  • The controlled modification of superconductivity by any means is a long-standing issue in low-temperature physics. In this work, we present data on the control of the superconducting properties of conventional low critical-temperature (T C ) Nb thin films with thickness (d Nb ) = 15 and 20 nm under application of reconfigurable strain, S induced by an external electric field, and E ex to a piezoelectric (PE) single crystal, namely (1 − x)Pb(Mg 1/3 Nb 2/3 )O 3 − x PbTiO 3 (PMN-PT) with x = 0.30–0.31. The experimental results (reduction of T C and critical current (J C ) on the order of 6% and 90–100%, respectively) are nicely reproduced with a phenomenological model that incorporates the constitutive relation S(E ex ) that describes the electro-mechanical response of the PE crystal to well-established formulas that describe T C and J C of the SC thin films.
