Description

technical field

[0001] The invention relates to the technical field of ferrite materials, in particular to a soft ferrite material and a preparation process thereof. Background technique

[0002] As the speed of the development of electrons in the direction of high frequency continues to accelerate, the requirements for the high-frequency core loss characteristics of magnetic materials are also getting higher and higher, and the various core materials currently used have the same core loss in the high-frequency band. The sharp increase cannot meet the requirements of use. Therefore, it is necessary to develop a soft ferrite material used under high frequency conditions to adapt to this change. Contents of the invention

[0003] The technical problems of the basic background technology, the present invention proposes a soft ferrite material with low core loss in high frequency state.

[0004] A kind of soft magnetic ferrite material proposed by the present invention, its r...
