Parametric plots of the remagnetization versus demagnetization remanences were found for four metallic ferromagnets—nickel wire, two types of AlNiCo, and samarium cobalt 2:17. These plots, known as Henkel plots, were compared to Wohlfarth’s model for noninteracting magnetic particles and several Preisach models. The remagnetization data were taken with a variety of paths to the net zero magnetization state. The resulting Henkel plots exhibit similarities to independent Monte Carlo simulations. The differences can be mostly explained by considering that the magnetization in the metallic ferromagnets occur by domain wall motion.

退磁技术对金属铁磁体剩磁测量的影响 IEEE TRANSACTIONS ON MAGNETICS

发现了四种金属铁磁体（镍线、两种类型的 AlNiCo 和钐钴 2:17）的再磁与退磁剩磁的参数图。这些被称为汉克尔图的图与 Wohlfarth 的非相互作用磁性粒子模型和几个 Preisach 模型进行了比较。再磁化数据是通过多种路径获取到净零磁化状态的。由此产生的汉高图表现出与独立蒙特卡罗模拟的相似之处。考虑到金属铁磁体中的磁化是由畴壁运动产生的，主要可以解释这些差异。
