YIG: Bi₂O₃ Nanocomposite Thin Films for Magnetooptic and Microwave Applications

Figure 2

Measured specific Faraday rotation data points of annealed YIG thin films and different Y₃Fe₅O₁₂-Bi₂O₃ nanocomposite thin films. The specific Faraday rotation measurements for all samples were performed using a 532 nm polarized light source and a custom-made electromagnet used in conjunction with Thorlabs PAX polarimeter system.
