Superconductivity in Sm-doped 1,3,5-triphenylbenzene

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.
