Description

technical field [0001] The invention belongs to the field of functional materials, in particular to a magnetic alloy material. Background technique [0002] In the prior art, magnetic materials, especially magnetic materials, are used to produce high-frequency transformers, magnetic heads and other products that need to utilize the characteristics of magnetic materials. Magnetic materials refer to magnetic materials that have demagnetization properties compared with permanent magnet materials. At present, the production of main magnetic materials is basically made of ferrite materials. The main characteristics of this type of ferrite materials are high resistivity and small high-frequency eddy current loss. However, the magnetic products prepared by this material have low saturation magnetic induction intensity and poor temperature characteristics, and can only be used in the range of temperatures below 100 ° C. When the temperature exceeds this range, its performance will ...
