Abstract
Coexistence of Superconductivity and magnetism has always been the appealing area of interest for studying condensed-matter physics. Various current research efforts in strongly correlated systems focus on the interplay between magnetism and superconductivity. We report a study on the theoretical investigation of the coexistence of superconductivity and antiferromagnetism in Ce2PdIn8 superconductor. Hamiltonian model, double time temperature dependent Green's function formalism and a suitable decoupling approximation technique has been applying to show the coexistence of superconductivity and antiferromagnetism in Ce2PdIn8 superconductor. The phase diagrams of superconducting gap parameter (Δ) versus temperature (T), the superconducting transition temperature (TC) and antiferromagnetism order temperature (TN) versus antiferromagnetic order parameter (η) have been plotted. Finally, by combining the two phase diagrams, coexistence of superconductivity and antiferromagnetism in Ce2PdIn8 superconductor has been demonstrated. The model employed in this work, shows that, there is a common region where both superconductivity and antiferromagnetism can possibly coexist in superconducting Ce2PdIn8.
