다국어 초록 (Multilingual Abstract)
Magnetic properties of sintered Fe-79Ni-4Mo cores made of centrifugal atomized powders were investigated. Hc and μ_α of the cores sintered at 1350 ℃ for 2 hours measured at 60 ㎐ at a magnetic field of 10 Oe showed the best properties. Particularly the properties of Hc and μα measured at low field (＜ 0.2 Oe) were found to increase with increasing the particle size of the core samples. It resulted from the domain wall motion depending on the grain size of sintered bodies. The best D. C magnetic properties of Hc and μmax were 0.085 Oe and 40000, respectively. A. C properties of the same cores showed the μα of 11000. The magnetic properties of sintered cores always exhibited an enhanced AC/DC performance by using the powders mixed with two different particle sizes. Those properties of cores are expected to apply for current transformer.
