METHOD FOR PRODUCING COBALT FERRITE PARTICLES AND COBALT FERRITE PARTICLES PRODUCED BY SAME

Provided are magnetic particles (cobalt ferrite) having a micrometer-order average particle diameter and similar particle diameters. A cobalt ferrite precursor is heated in the presence of a sulfite, thereby obtaining intended cobalt ferrite magnetic particles.
