摘要： There is disclosed a magnetic ferrite material obtained by calcining a raw material, forming a calcined powder into a desired shape and sintering to contain Fe2O3, MnO and ZnO as main components, the magnetic ferrite material with a low power loss is realized by setting the coefficient of variation (CV value) of the content of a Ca component precipitated along a grain boundary in a range of 1 to 60%, and the magnetic ferrite material is manufactured by calcining the raw material containing Fe2O3, MnO and ZnO as the main components to obtain the calcined powder in which that the S component content is in a range of 1 to 200 ppm, and forming the calcined powder into the desired shape and sintering.
