摘　　要：Superconductivity(SC)was experimentally observed for the first time in antimony polyhydride.The diamond anvil cell combined with a laser heating system was used to synthesize the antimony polyhydride sample at high pressure and high temperature.In-situ high pressure transport measurements as a function of temperature with an applied magnetic field were performed to study the SC properties.It was found that the antimony polyhydride samples show superconducting transition with critical temperature T_(c)116 K at 184 GPa.The investigation of SC at magnetic field revealed the superconducting coherent length of∼40Åbased on the Ginzburg Landau(GL)equation.Antimony polyhydride superconductor has the second highest T_(c)in addition to sulfur hydride among the polyhydrides of elements from main groups IIIA to VIIA in the periodic table.
