Phase diagrams and magnetic properties of a ferrimagnetic cylindrical core/shell spin-1 Ising nanowire

A Monte Carlo Simulation has been used to study the critical behavior of the magnetic spin-1 Ising nanowire on an hexagonal lattice structure. Our system consists of a ferromagnetic core with two shells, coupled antiferromagnetically with a surface shell. The effects of the crystal field, the shell and the core/shell interactions on the behavior of the system are examined. We found that the system exhibits one or two compensation points, the first and the second order transitions. Moreover, we have obtained that the critical point depends on the shell coupling. - Highlights: • Phase diagrams and magnetic properties are examined for a spin 1 Ising nanowire. • The system is studied by using Monte Carlo Simulation. • The possibility of two compensation points has been found. • The system exhibits a first order phase transition
