摘要： PROBLEM TO BE SOLVED: To provide a magnetic core material for AC having high saturation magnetization, unlimited magnetization direction, low iron loss, and excellent shape flexibility. SOLUTION: This magnetic core material consists of a structure wherein a metal ferromagnetic substance phase consisting of Fe-Si or Fe-Co is separated by a semiconductor phase consisting of FeS. The manufacture thereof is carried out by the casting in a mold with a predetermined shape after the dissolution. At that time, cooling is performed on the condition that the cooling rate of the surface layer is ≤10°C/sec so that FeS crystallizes out like a network to be able to obtain the magnetic core material consisting of the structure wherein the metal ferromagnetic substance phase is separated. More preferably, magnetic annealing is carried out after the cooling. As a result, the magnetic core material with a smaller iron loss can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
