摘要：
本工作处于一个更大项目的早期阶段，该项目旨在回答 Preisach 图是否真正能作为磁性材料指纹的问题。更具体地说，我们关注磁滞的 Preisach 模型究竟是否包含任何物理内容，还是仅仅是一种方便的建模工具。为此，我们研究一个非常简单、因而完全可解析处理的机械系统，该系统受到外力作用。尽管模型简单，它却捕捉了真实磁性材料的所有基本特征，即磁滞行为、矫顽力、剩磁以及高场下的饱和。主磁滞回线的整体形状以及一阶反转曲线（FORC）都得到了相当正确的再现；它们与在磁性材料中观察到的结果非常相似。该模型本质上由一根单独的、弹簧加载的、刚性且可转动的杆组成，并具有非零摩擦力矩。该杆在外力方向上的投影长度被等同于磁化强度。摩擦力矩和弹簧常数是我们模型中仅有的两个可自由调节的参数。在此，我们研究并展示它们对所推断 Preisach 图的影响。
英文摘要：
This work is an an early stage of a larger project aiming at answering the question whether or not the Preisach map is really fingerprinting magnetic materials. More precisely, we are interested whether Preisach model of magnetic hysteresis indeed contains any physics or is just a convenient modeling tool. To this extent we study a very simple mechanical system, thus fully tractable, subjected to the external force. Despite of its simplicity, our model captures all the fundamental features of real magnetic materials, namely their hysteretic behavior, coercivity, remanent magnetization and saturation at high fields. Both the overall shape of major hysteresis loop as well as First Order Reversal Curves (FORC's) are reproduced quite correctly; they are very similar to those observed in magnetic materials. The model essentially consists of a single, spring loaded, rigid and rotative bar with non-zero friction torque. The length of a projection of this bar onto the direction of an external force is identified with magnetization. The friction torque and the spring constant are the only freely adjustable parameters of our model. Here we investigate, and present, their influence on the inferred Preisach maps.
