under pressure*

Systematic high-pressure studies have been carried out on the type-II Weyl semimetal candidate Mo_0.50W_0.50Te₂ using a diamond anvil cell in order to determine the effects of pressure on its magnetotransport properties. Superconductivity was successfully induced under 1.1 GPa with a superconducting transition temperature (T_c) of 2.6 K. T_c was found to continuously increase with increasing pressure, reaching a maximum value of 5.8 K under 14.3 GPa. With further increasing pressure above 14.3 GPa, the T_c remains constant and then begins to decrease at 17.5 GPa. The dome-shaped T_c - P phase diagram was mapped out for pressure up to 42 GPa. Under pressure, the magnetoresistance of Mo_0.50W_0.50Te₂ is suppressed and its Hall coefficient changes sign. Details of the above results will be discussed.
