IRON-BASED SOFT MAGNETIC MATERIAL, METHOD OF MANUFACTURING IRON-BASED SOFT MAGNETIC MATERIAL, AND IRON-BASED SOFT MAGNETIC CORE

摘要

To provide an iron-based soft magnetic material capable of sufficiently reducing eddy current loss, and an iron-based soft magnetic core comprising the iron-based soft magnetic material, and further to provide a method of manufacturing such an iron-based soft magnetic material.SOLUTION: An iron-based soft magnetic material contains, as main constituents, iron, copper and chalcogen at least containing sulfur. The percentages of contents of these constituents are kept within a specific range, and a material including at least one element selected from the group consisting of titanium, zirconium, vanadium, niobium, chrome, molybdenum, tungsten, manganese, zinc, boron, aluminum, gallium and silicon is blended with the iron-based soft magnetic material to form molten metal. By quenching the molten metal, a cell wall structure can be achieved, the cell wall structure including a cell consisting of a matrix phase containing iron as a main constituent and a cell boundary phase existing at a cell boundary and containing a copper-containing sulfide as a main constituent.SELECTED DRAWING: Figure 1
