Abstract
A cluster of silicate minerals known as garnet is widely used as abrasives and gemstones, has now found an application as smart nonmaterial. The garnet possesses a unique feature of having different chemical composition with similar crystal form and physical properties. Yttrium iron garnet (YIG) also popularly known as iron yttrium oxide, is an example of lab grown garnet. It can have chemical composition of Y3Fe5O1 or Y3Fe2(FeO4). The YIG exhibits a ferrimagnetic nature, with a Curie temperature of 560 K. The chapter focuses on the research around YIG with a mention on fabrication methods and applications.
