本文讨论了金属和化合物中过渡元素原子磁矩之间有效交换相互作用的主要机制。其目的是提出明确的物理图片和明确定义的术语的基础上的电子结构的第一性原理计算的机制。讨论涵盖过渡金属，合金和化合物，包括Nd-Fe-B，磁性半导体和双钙钛矿。有效交换作用的机制可分为双交换作用、杂化引起的p-d交换作用和超交换作用。命名和精确的定义进行了讨论，在其历史背景。
I discuss principal mechanisms of the effective exchange interaction between magnetic moments of transition element atoms in metals and compounds. The purpose is to present clear-cut physical pictures and well-defined terminology of the mechanisms on the basis of the electronic structures revealed by the first principles calculations. Discussion covers transition metals, alloys and compounds including Nd-Fe-B, magnetic semiconductors, and double perovskites. The mechanisms of the effective exchange interaction are categorized into the double exchange interaction, the p-d exchange interaction due to hybridization and the superexchange interaction. The naming and precise definitions are discussed in their historical context.
