YIG
YIG has superior optical and microwave properties. In the field of optics, the Faraday effect of yttrium iron garnet can be used to manufacture mid-infrared isolators, laser modulators, fiber optic current sensors and other products; In the field of microwaves, YIG has high Q resonance characteristics, which can be used to manufacture magnetic resonance filters, tuned oscillators, bandpass filters and other products.
Yttrium iron garnet, referred to as YIG, chemical formula Y3Fe5O12, is a garnet-type ferrite, is an iron oxide synthetic crystal with a number of magnetic properties, belonging to the cubic crystal system, has good gyromagnetic effect, low saturation magnetization, small resonance line width, high resistance, low dielectric loss and other advantages. YIG is widely used in optics, microwave field and is an important ferrite product type.
