Abstract

We report the discovery of superconductivity at about 4.3 K in samarium-doped 1,3,5-triphenylbenzene. Using a solid-state reaction method, samarium-doped 1,3,5-triphenylbenzene samples are successfully synthesized. These samples are characterized by magnetization, x-ray diffraction, scanning electron microscope, and energy-dispersive spectroscopy measurements. The x-ray diffractions reveal that the sample crystallizes in the space group 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 previous reports of the superconductivity in other aromatic hydrocarbons. Magnetization hysteresis loops of the sample show that it is a typical type II superconductor. Our results indicate possible superconductivity in this organic material.
