摘要：
A hexagonal nanowire consisting of a ferromagnetic spin-1/2 core, spin-1 inter core/shell and spin-3/2 outer shell coupled with ferrimagnetic interlayer couplings has been studied by the use of Monte Carlo simulation based on the heat bath algorithm. The exchange interactions and the uniaxial anisotropy effects on the magnetic properties of the system have been discussed. We found that, the system exhibits the compensation phenomenon, the first and the second order transitions. Moreover, we have obtained that, the existence of the tricritical point depend on the surface shell interaction. (C) 2017 Elsevier B.V. All rights reserved.
