Fig. 3: Tensile strain applied to Sr2RuO4.
From: Direct evidence for the absence of coupling between shear strain and superconductivity in Sr2RuO4
Variations of Tc measured by mutual inductance with an assembly of a tensile piezoelectric device and an Sr2RuO4 sample. A quadratic dependence on uniaxial strain is observed, with a minimum at Δεxx ~ + 0.1% that indicates presence of pre-strains. To compare the Tc resolution with the shear data, the grey shaded region indicates an interval of ± 0.6 mK.
