Claims16
A metal magnetic material, comprising
- zinc added to a metal magnetic alloy powder made of iron and silicon.
A metal magnetic material, comprising
- zinc added to a metal magnetic alloy powder made of iron and silicon, and wherein
- a reaction product of the zinc and the metal magnetic alloy powder is generated by a heat treatment.
A metal magnetic material, comprising
- zinc added to a metal magnetic alloy powder made of iron and silicon, and wherein
- a reaction product of the zinc and the metal magnetic alloy powder is generated by a heat treatment so that an oxide of the metal magnetic alloy powder due to the reaction product is present.
A metal magnetic material, comprising
- zinc added to a metal magnetic alloy powder made of iron and silicon, and wherein
- a reaction product of the zinc and the metal magnetic alloy powder is generated by a heat treatment so that the reaction product is formed near a surface of the metal magnetic alloy powder.
An electronic component, comprising
- an element body formed of a metal magnetic material acquired by adding zinc to a metal magnetic alloy powder made of iron and silicon, wherein
- a reaction product of the zinc and the metal magnetic alloy powder is generated in the element body, and wherein
