Abstract
The method of manufacturing hexagonal ferrite magnetic particles, which includes providing hexagonal ferrite magnetic particles by conducting calcination of particles comprising an alkaline earth metal salt and an iron salt to cause ferritization; and further includes causing a glass component to adhere to the particles and then conducting the calcination of the particles to form a calcined product in which hexagonal ferrite is detected as a principal component in X-ray diffraction analysis; and removing the glass component from a surface of the calcined product that has been formed.
