Abstract: A method is provided which comprises preparing pulverized ferrite having a magnetoplumbite type crystal structure of hexagonal system, mixing and kneading the ferrite with a viscous binding agent, subjecting the mixture to rolling to form a sheet-like mass with the easy axis being orientated in the direction perpendicular to the plane of the ferrite sheet by making use of anisotropic configuration of the crystal grains of the pulverized ferrite, rolling the sheet-like mass into a desired shape, and sintering and magnetizing the shaped ferrite.
