论文摘要
Stoner-Wohlfarth（SW）模型是单域颗粒的磁性磁滞的经典模型。对于有限温度下的二维磁体，必须扩展SW模型以包括内在的强旋转波动。我们预测2D和3D磁体之间的几种根本不同的磁滞性能。传统SW模型中称为小行星图的磁化开关图与横向和纵向磁场相对于温度高度且不对称。我们的结果为基于2D磁性材料的Spintronics应用提供了新的见解。
The Stoner-Wohlfarth (SW) model is a classical model for magnetic hysteresis of single-domain particles. For two-dimensional magnets at finite temperature, the SW model must be extended to include intrinsic strong spin fluctuations. We predict several fundamentally different hysteresis properties between 2D and 3D magnets. The magnetization switching diagram known as the Asteroid figure in the conventional SW model becomes highly temperature dependent and asymmetric with respect to the transverse and longitudinal magnetic fields. Our results provide new insights for 2D magnetic materials based spintronics applications.
