Magnetic material, method for producing magnetic material, and inductor element |
摘要 |
A magnetic material is disclosed, which includes magnetic particles containing at least one magnetic metal selected from the group including Fe, Co and Ni, and at least one non-magnetic metal selected from Mg, Al, Si, Ca, Zr, Ti, Hf, Zn, Mn, rare earth elements, Ba and Sr; a first coating layer of a first oxide that covers at least a portion of the magnetic particles; oxide particles of a second oxide that is present between the magnetic particles and constitutes an eutectic reaction system with the first oxide; and an oxide phase that is present between the magnetic particles and has an eutectic structure of the first oxide and the second oxide. |

1. A magnetic material, comprising:
magnetic particles comprising at least one magnetic metal selected from the group consisting of iron (Fe), cobalt (Co) and nickel (Ni), and comprising at least one non-magnetic metal selected from the group the consisting of magnesium (Mg), aluminum (Al), silicon (Si), calcium (Ca), zirconium (Zr), titanium (Ti), hafnium (Hf), zinc (Zn), manganese (Mn), a rare earth element, barium (Ba) and strontium (Sr); a first coating layer of a first oxide that covers at least a portion of the magnetic particles; oxide particles of a second oxide that is present between the magnetic particles, the second oxide forming a eutectic reaction system with the first oxide; and an oxide phase that is present between the magnetic particles and has an eutectic structure of the first oxide and the second oxide. |
