Magnetic properties of Kekulene structure: A Monte Carlo study

The magnetic properties of magnetic Kekulene structure with mixed spins-5/2 and 2 Ising model have been studied using Monte Carlo simulations. The ground state phase diagrams of system Ising model and the thermal magnetization have been obtained. The transition temperature has been determined. The effect of reduced crystal field and exchange interactions on the magnetic Kekulene structure are studied. Finally, the magnetic hysteresis cycles of the mixed spins-5/2 and 2 Ising model on a magnetic Kekulene structure have been obtained for a several values of crystal field, exchange interactions and temperatures values. The superparamagnetism behavior is observed in Kekulene structure.
