光是一种电磁现象,并具有波粒二象性。磁性是物质的最基本最普通的属性,磁场是物质的一种特殊存在形态。因此探索光、物质和磁场三者之间相互作用的内在联系,是现代物理学中的一个重要分支之一——磁光学。研究材料的磁光性质是认识基本磁性的有力手段,磁光学就是研究在磁场作用下所引起的各种光学现象。本文介绍了磁光效应当中的一种效应,即法拉第磁光效应以及它的测量方法和应用举例,分二期连载。
Light is an electromagnetic phenomenon and has wave-particle duality. Magnetism is the most basic and common property of matter. The magnetic field is a special existence of matter. Therefore, it is an important branch in modern physics to explore the internal relations among light, matter and magnetic field - magneto-optics. The study of the magneto-optical properties of materials is a powerful means of understanding the basic magnetism. Magneto-optical studies the various optical phenomena caused by the action of a magnetic field. This article describes one of the effects of magneto-optical effect, that Faraday magneto-optical effect as well as its measurement methods and application examples, divided into two consecutive series.
