Monte Carlo study of the random magnetic field effect on the phase diagrams of a spin-1 cylindrical nanowire
In this work, the phase diagrams and the tricritical behavior of a cylindrical nanowire, consisting of a ferromagnetic core of spin-1 atoms surrounded by a ferromagnetic shell of spin-1 atoms with ferromagnetic or antiferromagnetic interfacial coupling are studied in the presence of a random magneti...

description | In this work, the phase diagrams and the tricritical behavior of a cylindrical nanowire, consisting of a ferromagnetic core of spin-1 atoms surrounded by a ferromagnetic shell of spin-1 atoms with ferromagnetic or antiferromagnetic interfacial coupling are studied in the presence of a random magnetic field. Based on Metropolis algorithm, Monte Carlo simulation has been used to investigate the effects of the exchange coupling of the shell, the interfacial coupling, and the random magnetic field on the critical behavior of the nanowire. Depending on the values of the system parameters, different types of phase diagrams were found. A variety of multicritical points such as tricritical point, isolated critical point, and triple point are obtained. In addition, the compensation temperature can be appear in the ferrimagnetic system case.
•Phase diagrams of a spin-1 nanowire are examined by the MCS.•The effect of the random magnetic field on the magnetic properties is studied.•Different types of the phase diagrams are obtained.•The dependence of the magnetization and susceptibility on the temperature are investigated. |
