In the present paper, existence of spin glass state using Ising spin model with Edwards-Anderson type of interactions has been investigated by employing numerical simulation (Monte Carlo) technique. The study shows a phase transition from paramagnetic state to spin glass state when far apart spins are included in addition to nearest neighbor ones using power law decaying interactions.
