Based on the Ising model, using the Monte Carlo method, we examine the magnetic and thermodynamic characteristics of a ferrimagnetic hexagonal nanowire with spin-5/2 and spin-7/2 of alternate layer structure under external and longitudinal crystal magnetic fields, in particular the physical effect of the external magnetic field on compensation behavior. Moreover, the phase diagrams in the ( T , D / J s ), ( T , J int / J s ), and ( T , J σ / J s) planes have been detailed. Consequently, we have obtained single and double compensation temperatures for the determined longitudinal crystal and external field parameters. The magnetizations of type-N, type-Q, and type-M have been found for certain parameter values in our system. This research was compared with other theoretical and experimental findings.

In this work, the thermodynamic and magnetic properties such as total and partial magnetizations, magnetic susceptibility, internal energy, total specific heat, magnetic hysteresis loops and compensation temperature of a ferrimagnetic mixed spins-3/2 and spins-5/2 hexagonal Ising nanowire, have been determined by using Monte Carlo method based on the Metropolis algorithm. The effects of the longitudinal crystal field, the exchange interactions and the temperature on the magnetic properties and hysteresis loops are examined in detail for different values of the system parameters. Moreover, different interesting magnetic phenomena were obtained, such as the seven and triple hysteresis loops at low temperatures, the tricritical point and compensation behavior under certain physical parameters were detected. Our results are also compared with some experimental and theoretical results. [ABSTRACT FROM AUTHOR]
