摘要

PPROBLEM TO BE SOLVED: To provide a high-frequency magnetic material usable in the high-frequency domain of ≥100 MHz, and to provide a part using the same. PSOLUTION: The high-frequency magnetic material contains a metal oxide low in reducibility and metallic particles of one or more selected from the group consisting of Fe, Co, and alloys based on them. The material is manufactured with a high yield because the metallic particles are precipitated by reducing a multiple oxide, preferably by reducing a complete solid solution. A high-frequency magnetic material manufactured in this way is used with various high-frequency magnetic parts such as inductance elements or electromagnetic wave absorbers.
