Magnetic Properties of the Spins-5/2 and 3/2 Ising Octahedral Chain: A Monte Carlo Simulation

Abstract

Spins-5/2 and 3/2 Ising octahedral chain with regularly alternating monomeric and square plaquette sites is investigated using Monte Carlo simulations. The ground state phase diagrams of octahedral chain have been found for different blocks [Formula: see text] and for a several reduced crystal fields. The magnetization and magnetic susceptibilities of the mixed spins Ising octahedral chain have been obtained. The variation of reduced the transition temperatures with 1/[Formula: see text] has been determined. The magnetic hysteresis cycles of the mixed spins Ising octahedral chain for several blocks, [Formula: see text], for several reduced crystal fields and reduced exchanges interactions for a weak a zero crystal field have been investigated.
