摘　　要：We used a highly sensitive AC magnetic susceptibility technique to probe superconductivity in elemental titanium(Ti)under extreme pressures to 120 GPa in a diamond anvil cell(DAC).The measurements reveal that the critical temperature(Tc)of Ti rises monotonically with increasing pressure,reaching 6.1 K at 120 GPa.Our results confirm the bulk nature of the superconductivity in Ti,as evidenced by a robust diamagnetic response in the AC magnetic susceptibility.Our work provides a routine technique to probe Meissner effect of elemental superconductors at megabar pressures.
