摘要磁学自古以来就是一个研究的话题。从每年发表的论文数量来看，关注磁性材料性质的科学家群体正在极大地扩大。之所以对这一领域产生极大的兴趣，不仅是因为这些材料在技术上得到了广泛的应用，也是因为它有机会为理解基础物理做出贡献。本文所称的磁性材料，是指在一定温度以下自发表现出磁性有序的物质。这种磁序可以是铁磁性、铁磁性、反铁磁性或亚磁性类型。然而，在这些磁性结构中，铁磁性似乎是最重要的。铁磁性的定义是原子磁矩在相对较大的固体区域内自发平行排列。磁序仅限于含有电子壳层不完全填充的元素的化合物，例如，转变…
Abstract Magnetism has been a topic of study since the ancient times of science. Judging by the number of papers appearing each year, the group of scientists concerned with the properties of magnetic materials is vastly expanding. The reason for the great interest in this field is not only the wide application which these materials have found in technology, but also the chance to contribute to the understanding of basic physics. The term “magnetic material” in this article refers to a substance which spontaneously exhibits magnetic order below a certain temperature. This magnetic order can be of the ferro-, ferri-, antiferro-, or metamagnetic kind. However, within these magnetic structures ferromagnetism appears to be the most important one. Ferromagnetism is defined by the spontaneous parallel alignment of atomic magnetic moments over relatively large regions of a solid. Magnetic order is limited to compounds which contain elements with incompletely filled electron shells, as for example, the transition ...
