AI总结:

首次实验合成了锑多氢化物并在184 GPa下发现Tc 116K的超导性,基于GL方程测得其超导相干长度约40埃,是主族多氢化物中Tc第二高的超导体。

摘要:

首次在实验中观察到锑多氢化物的超导性(SC)。使用金刚石压砧结合激光加热系统,在高温高压条件下合成了锑多氢化物样品。在施加磁场下进行了原位高压输运随温度变化的测量,以研究其SC性质。发现锑多氢化物样品在184 GPa下表现出临界温度Tc 116 K的超导转变。基于Ginzburg Landau(GL)方程对磁场下SC的研究表明,超导相干长度约为40埃。在元素周期表IIIA至VIIA主族元素的多氢化物中,锑多氢化物超导体是除硫化氢外Tc第二高的。

英文摘要:

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