a–c Mutual inductance M of the sense coils versus temperature for samples 2–4, at various applied stresses σzz. The lines indicate the selected thresholds for determination of Tc. For sample 2, under large ∣σzz∣ a tail appears on the transitions, which we attribute to in-plane stress, and a low threshold is chosen to avoid this tail. d Tc versus stress for all the samples. The stress scales for samples 1–3 are scaled to bring dTc/dσzz into agreement with that of sample 4 over the stress range labeled “fitted range”, − 0.92 to − 0.20 GPa.
