摘要：
In this work, we have used Monte Carlo Simulation technique (MCS) and effective field theory (EFT) to study the critical and the compensation behaviors of a terrimagnetic cylindrical nanowire. The system consists of a ferromagnetic spin S-A=1/2 core and a ferromagnetic spin S-B=1 surface shell coupled with an antiferromagnetic interlayer coupling Ii to the core. The effects of the uniaxial anisotropy, the shell coupling and the interface negative coupling on both the critical and compensation temperatures are investigated. (C) 2014 Elsevier By.
