The solid-state reaction method is a traditional approach for YIG synthesis, involving the high-temperature firing of a mixture of yttrium and iron oxides.

[4] This cost-effective technique can produce pure YIG crystals but requires careful control of temperature and atmosphere to prevent impurities.

[5] Liquid phase epitaxy (LPE) is another key method, especially for creating thin YIG films with excellent uniformity.

Ideal for optical and microwave devices, LPE enables precise film growth on substrates.

[citation needed] It also finds use in solid-state lasers in Faraday rotators, in data storage, and in various nonlinear optics applications.
