“Can you YIG it?

What is YIG? YIG (Yttrium Iron Garnet) is a synthetic Yttrium-Iron-Garnet having ferrimagnetic properties that is used especially as a filter for selecting or tuning microwaves. YIG and YIG Related Spheres and Crystalline Shapes are routinely used by manufactures of YIG-tuned devices such as: YIG-tuned Oscillators (YTOs), both Band-Pass and Band Reject Filters, Multipliers, Harmonic Generators, etc. These materials are also used in Faraday Rotators, Optical Isolators and Infrared Sensors.
