摘要

本文利用蒙特卡洛模拟全面探索了由σ=5/2 和 S=2 混合自旋组成的球形纳米结构的磁特性。通过系统地改变球内 σ 或 S 自旋的比例（p %），我们研究了系统的磁行为，包括磁化、磁滞回线、剩磁和矫顽力场。我们的研究结果为了解这种球形结构的磁行为机制提供了宝贵的见解，可能有助于推动从数据存储到生物医学设备等领域的发展。

Emergence of novel magnetic states in a spherical structure with mixed spins σ=5/2 and S=2: A Monte Carlo simulation study

This paper employs Monte Carlo simulations to comprehensively explore the magnetic properties of a spherical nanostructure composed of mixed σ=5/2 and S=2 spins. By systematically varying the proportion (p %) of σ or S spins within the sphere, we investigate the system magnetic behavior, including magnetization, hysteresis loops, remanence, and coercive field. Our findings offer valuable insights into the mechanisms governing the magnetic behavior of this spherical structure, potentially contributing to advancements in fields ranging from data storage to biomedical devices.

期刊介绍： Physica A: Statistical Mechanics and its Applications Recognized by the European Physical Society Physica A publishes research in the field of statistical mechanics and its applications. Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents. Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
