论文摘要
我们报告了在掺杂1,3,5-三苯基苯二掺杂的samarium中发现超导性的。通过使用固态反应方法，成功合成了掺杂的1,3,5-三苯基苯苯样品。这些样品的特征是磁化，X射线衍射（XRD），扫描电子显微镜（SEM）和能量色散光谱（EDS）测量。 X射线衍射表明，样品在$ p2/m $的空间组中结晶。磁化测量值显示在约4.3 K处的超导过渡。但是，超导屏蔽部分仅约1％，这与先前关于其他芳族烃中超导性的报道相似。样品的磁化磁滞回路（MHL）表明它是典型的II型超导体。
We report the discovery of superconductivity at about 4.3 K in the samarium doped 1,3,5-triphenylbenzene. By using a solid state reaction method, the samarium doped 1,3,5-triphenylbenzene samples are successfully synthesized. These samples are characterized by magnetization, X-ray diffraction (XRD), scanning electron microscope(SEM) and energy dispersive spectroscopy (EDS) measurements. The X-ray diffractions reveal that the sample crystallizes in a space group of $P2/m$. The magnetization measurements reveal a superconducting transition at about 4.3 K. However, the superconducting shielding fraction is only about 1%, which is similar to the previous reports of the superconductivity in other aromatic hydrocarbons. Magnetization hysteresis loops (MHLs) of the sample show that it is a typical type-II superconductor.
