我们发现，在各种过渡金属系统中的巡回磁性不能用熟悉的Stoner模型（刚性带理论）来描述。在元素反铁磁体、某些杂质系统（过渡金属中的过渡金属）和某些过渡金属化合物中发现的磁性被证明是由相邻过渡金属原子d态之间共价相互作用的自旋依赖性变化引起的。
We show that itinerant magnetism in a variety of transition‐metal systems cannot be described by the familiar Stoner model (rigid‐band theory). Magnetism as found in elemental anti‐ferromagnets, in certain impurity systems (transition metals in transiton metals), and in certain transition‐metal compounds is shown to arise from spin‐dependent changes in the covalent interactions between the d states of neighboring transition‐metal atoms.
