钇铁柘榴石(YIG),具有很窄的谐振宽度和低饱和磁化强度,广范地应用于制备微波器件、如可调振荡器、微波滤波器、限辐器、预选器、后选器等。利用YIG的磁光特性、可在光通信、光存储、光记录、激光光谱等中得到应用。但是钇铁柘榴石与其它宝石一样,自然形成的这种晶体是非常稀有的,一般应用的都是人工制备的。由于这种晶 Yttrium iron garnet (YIG) has a very narrow resonant width and low saturation magnetization and is widely used in the preparation of microwave devices such as tunable oscillators, microwave filters, beam limiters, preselection, post-selectors, etc. . The use of YIG magneto-optical properties, can be used in optical communications, optical storage, optical recording, laser spectroscopy and so on. However, yttrium iron garnet, like other gems, naturally forms such crystals that are very rare and are generally applied by hand. Because of this crystal
