Title:
MAGNETIC CORE AND COIL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2018/052108
Kind Code:
A1
Abstract:
Provided are: a magnetic core having a high initial permeability; and a coil component using same. This magnetic core exhibits, in an X-ray diffraction spectrum, a peak intensity ratio (P1/P2) of not higher than 0.015 between a peak intensity P1 that is of a diffraction peak of a Fe oxide having a corundum structure and that appears in the vicinity of 2θ=33.2°and a peak intensity P2 that is of a diffraction peak of a Fe-based alloy having a bcc structure and that appears in the vicinity of 2θ=44.7°, and a peak intensity ratio (P3/P2) of 0.015-0.050 between a peak intensity P3 that is of a superlattice peak of a Fe3Al ordered structure and that appears in the vicinity of 2θ=26.6° and the peak intensity P2.
