摘要

"我们在基于波哥留波夫不等式的均场理论框架内，以及通过 Metropolis 算法进行蒙特卡罗模拟的基础上，研究了具有核壳结构的六角纳米管的磁特性和相图。我们详细研究了不同的外变耦合和晶体场对系统相图的影响。通过这项研究，我们发现了一些有趣的临界现象，尤其是补偿行为。此外，我们还研究了与每个相图相对应的磁化行为，以验证所获得的结果"。

Magnetic Properties of a Mixed Spin-1/2 and Spin-7/2 Hexagonal Core-Shell Nanotube

"The magnetic properties and phase diagrams of a hexagonal nanotube with core-shell structure have been examined within the framework of the mean field theory based on the Bogoliubov inequality as well as the Monte Carlo simulation via the Metropolis algorithm. We have studied in detail the influences of the different ex- change couplings and the crystal field on the phase diagrams of the system. This study allowed us to discover the existence of interesting critical phenomena, in particular the compensation behavior. Moreover, we have investigated the behavior of the magne- tizations corresponding to each of the phase diagrams in order to verify the obtained results."

期刊介绍： Romanian Journal of Physics was first published in 1992 as a continuation of the former Revue Roumaine de Physique (ISSN: 0035-4090), a journal publishing physics and engineering scientific papers established 1956 with deep roots in the early history of the modern Romanian physics. Romanian Journal of Physics is a journal of the Romanian Academy published by Editura Academiei Romane (eA). The journal has an international character intended for the publication of original physics contributions from various sub-fields including the following: -Theoretical Physics & Applied Mathematics -Nuclear Physics -Solid State Physics & Materials Science -Statistical Physics & Quantum Mechanics -Optics -Spectroscopy -Plasma & Laser Physics -(High Energy) Elementary Particles Physics -Atomic and Molecular Physics -Astrophysics -Atmosphere (Environmental) & Earth Science -Environmental Protection
