Abstract:
This thesis investigates the influence of magnetic ordering on superconductivity in the compound. Utilizing a
comprehensive model Hamiltonian and employing the equation of motion approach within Green's function
formalism; we explore the intricate interplay between various parameters governing these phenomena. Our
analysis reveals a remarkable exponential increase in the superconducting transition temperature (TC) with the
coupling strength (λ), indicating enhanced superconductivity driven by greater electron density and electron phonon interaction. Additionally, we observe a decline in the superconducting order parameter with increasing
temperature, highlighting the dominant role of thermal energy in suppressing superconductivity. Furthermore,
heightened magnetic order is found to disrupt superconductivity, while increased spin order sustains magnetic
behavior even at elevated temperatures. Theoretical calculations for Tc demonstrate excellent agreement with
experimental values, validating our theoretical framework and providing valuable insights into the complex
relationship between superconductivity and magnetism.
