Problems solved by technology

[0002] The BiCaV material in the gyromagnetic polycrystalline ferrite material is generally used as a small line width substitute material, and has been used for non-power devices with low requirements. The loss is large, and it is basically not used for power devices; Magnetic polycrystalline materials generally use materials containing Y (yttrium oxide) in a large amount, and yttrium oxide, as a rare earth oxide, has high cost, high sintering temperature, and large energy consumption.
