Problems solved by technology

However, since metal Co is a scarce resource in our country and relies heavily on imports, the price of Co is relatively high. Adding a large amount of metal Co content to the alloy will undoubtedly greatly increase the preparation cost, making the alloy unsuitable for industrial production.

Abstract

The invention relates to a novel magnetic material, and belongs to the field of functional materials. The provided novel magnetic material is low in cost and comprises, by atomic percent, 2-7% of Nd, 2-7% of Nb, 1-5% of Dy, 3-10% of Si, 8-12% of B, 1-3% of Zn, 1-5% of Ag and the balance iron. According to the magnetic material, a small amount of Nd, Nb and Dy are added, on the premise that Co is not added, the high Curie temperature of the material is guaranteed, high magnetic conductivity is also achieved under the high-temperature condition, and the cost of the magnetic material is reduced.

Description

technical field [0001] The invention relates to novel magnetic materials and belongs to the field of functional materials. Background technique [0002] With the development of science and technology, magnetic alloys are increasingly widely used in emerging technical fields such as electricity, electronics, computers, automatic control and electro-optics. Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetization after magnetization. The material that is easy to demagnetize after magnetization is called soft magnetic material, and the material that is not easy to demagnetize is called hard magnetic material. Generally speaking, the remanence of soft magnetic materials is small, and that of hard magnetic materials is relatively large. [0003] Among them, soft magnetic materials are often used to produce products with soft magnetic properties such as high-frequency transformers, choke coils, and ...
