Abstract

We report appearance of superconductivity in CeO0.5F0.5BiS2. The bulk polycrystalline samples CeOBiS2 and CeO0.5F0.5BiS2 are synthesized by conventional solid state reaction route via vacuum encapsulation technique. Detailed structural analysis showed that the studied CeO0.5F0.5BiS2 compound is crystallized in tetragonal P4/nmm space group with lattice parameters a=4.016(3) , c=13.604(2) . DC magnetization measurement (MT-curve) shows the ferromagnetic signal at the low temperature region. The superconductivity is established in CeO0.5F0.5BiS2 at by electrical transport measurement. Under applied magnetic field, both T (c) onset and T (c) (rho=0) decrease to lower temperatures and an upper critical field [H (c2)(0)] above 1.2 Tesla is estimated. The results suggest coexistence of ferromagnetism and superconductivity for the CeO0.5F0.5BiS2 sample.
