Abstract

The invention relates to a method of manufacturing magnet cores consisting of representatives of a special class of lithium-, copper-, zinc-, (cobalt-) ferrites, by sintering at temperatures which do not exceed 1100 DEG C. These cores may serve to replace, nickel-containing and hence more expensive, ferrite cores which may serve as "yoke" rings or as aerial rods.
