摘要

利用平均场方法，研究了铁磁构型下具有自旋1/2核和自旋5/2壳的六边形Ising纳米线的磁特性和相图。我们研究了晶体场和交换相互作用对纳米线临界和磁性行为的影响。结果揭示了一阶和二阶相变、临界孤立端点和补偿温度的出现。这些特性对于这些纳米线的技术应用来说是很有吸引力的。

Magnetic properties of a hexagonal Ising nanowire with spin-1/2 core and spin-5/2 shell

Using a mean-field approach, we investigated the magnetic characteristics and phase diagrams of a hexagonal Ising nanowire with a spin-1/2 core and a spin-5/2 shell in a ferrimagnetic configuration. We examined the impacts of crystal field and exchange interactions on the critical and magnetic behaviors of the nanowire. The results reveal the emergence of first- and second-order phase transitions, critical isolated end-points, and compensation temperatures. The properties identified could be fascinating for the technological uses of these nanowires.
