Hexagonal type Ising nanowire with core/shell structure: The phase diagrams and compensation behaviors

• Magnetic properties of the hexagonal Ising nanowire are investigated.
• We studied the effects of the Hamiltonian parameters on the phase diagrams.
• We obtained the four types compensation behaviors.
• Reentrant behavior is found depending on ratio of physical parameters.

The phase diagrams and compensation behaviors of a mixed spin (1/2-1) hexagonal Ising nanowire with core-shell structure are studied by using the effective-field theory with correlations. The effects of the interaction parameters and crystal field on the critical behaviors of the system are investigated, in detail. It has been found that the system shows first-order and second order phase transition, and tricritical point. Moreover, Q-, R-, S- and N-types of compensation behaviors in the Neél classification nomenclature as well as reentrant behaviors are observed in the system.
