Abstract
The method of manufacturing hexagonal ferrite magnetic particles comprises applying, in a water-based solution, an adhering matter comprising a glass component and an alkaline earth metal to iron oxide particles to which a surfactant adheres, and calcining the iron oxide particles to which the adhering matter adheres to obtain a calcined product in which a main component that is detected by X-ray diffraction analysis is hexagonal ferrite.
