Abstract

Abstract: By using the effective field theory based on a probability distribution method, the phase diagrams and the magnetic properties of an Ising nanowire in the presence of the biaxial transverse crystal-field are investigated. The effects of the biaxial transverse crystal field, the interfacial coupling and the exchange interaction in the surface on the phase diagram, the magnetization and the internal energy are examined. Some characteristic phenomena are found such as the tricritical behavior, the critical end point and the re-entrant phenomenon. Highlights: We have used the EFT, based on a probability distribution to study the phase diagrams and the magnetic properties of the nanowire. We have investigated the effects of the biaxial transverse crystal field, on the magnetic properties of the system. We have obtained the tricritical behavior, the critical end point and the reentrant phenomenon.
