“…Following the recent discovery of superconductivity near a ferromagnetic critical point in ruthenates [1] ,URhGe & UGe 2 [2,3,4] and superconductivity in antiferromagnetic insulators [5] force us to re estimate the behavior of simultaneous magnetism with superconductivity. The existence of superconductivity and magnetic order at different temperature ranges in different compounds has been seen for more than half a century [6,7,8,9], but still we don't know the exact coexistence of this order. In the present work an attempt is made to develop the microscopic theory of coexistence of superconductivity, ferromagnetism and antiferromagnetism by writing a Hamiltonian for this system.…”

In the age of technology, with smaller and smaller electronic components being used in a growing number of applications, one pertinent application of mathematics and physics is the study of superconductivity. Superconductive materials are capable of conducting electricity without any resistance and were first discovered by Kamerlingh Onnes in 1911 in a compound He at 4.2 K in what was to prove to be one of the most significant scientific breakthroughs of the 20th Century. Superconductivity and Magnetism are mutually exclusive to each other but the coexistence of both the phenomena leads to very interesting research of superconductivity at room temperature. In this paper, we have studied the effect of ferromagnetic and antiferromagnetic interactions on the superconducting transition temperature.
