Fig. 1: The superconductivity measurements.
From: Record high Tc element superconductivity achieved in titanium
a Temperature dependence of the electrical resistance of elemental metallic Ti (Sample 1) measured at high pressures. The inset is an enlarged view of the resistance curve, showing the superconducting transition in detail. b The resistance curves for Ti Sample 2. c The resistance curve measured at 248 GPa, where the derivative of the resistance with respect to temperature dR/dT is plotted to clearly show the onset Tc.
