摘要

蒙特卡洛模拟揭示了蜂窝状、卡戈米状和三角形纳米晶格中截然不同的磁性行为，这对磁性材料的开发至关重要。由于原子排列和几何形状的不同，蜂窝状纳米晶格显示出最早的磁化衰退，其次是卡戈米纳米晶格和三角形纳米晶格。增加线性耦合相互作用（J）、二次耦合相互作用（K）和外磁场会提高阻挡温度，而较高的晶体场（∣D∣）会降低阻挡温度。这些发现对于优化磁存储、传感器和纳米技术等应用中的磁稳定性和磁行为至关重要。

Monte Carlo simulations unveil magnetic differences in honeycomb, kagome, and triangular nanolattices

Monte Carlo simulations reveal distinct magnetic behaviors in honeycomb, kagome, and triangular nanolattices, crucial for magnetic material development. The honeycomb nanolattice shows the earliest magnetization decline, followed by the kagome and triangular nanolattices, due to differences in atomic arrangement and geometry. Increasing the linear coupling interaction (J), biquadratic coupling interaction (K), and external magnetic field raises the blocking temperature, while a higher crystal field (∣D∣) lowers it. These findings are pivotal for optimizing magnetic stability and behavior in applications like magnetic storage, sensors, and nanotechnologies.
