た。Nftoferrite has conventionally been used as a material that requires low core loss and high squareness in a high frequency range, such as in switching regulators, but ferrite has the disadvantage of a low saturation magnetic flux density B8 due to its nature. Amorphous magnetic materials with a large B8 are attracting attention as new materials to replace ferrite, but amorphous materials have lower electrical resistance than ferrite, and magnetic properties in the high frequency range where eddy current loss increases, compared to ferrite. It had the disadvantage of being inferior to.
