Abstract

The superconducting transition temperature Tc of vanadium has been measured up to 120 GPa by using a superconducting quantum interference device vibrating coil magnetometer. It was found that Tc increased with pressure with a coefficient of dTc/dP=0.1K/GPa and at the maximum pressure onset of superconductivity reached 17.2 K, the highest Tc among the elemental metals reported so far. Large signal to noise ratio was obtained for detecting the superconductivity of vanadium at megabar pressures in a diamond-anvil cell.
