Method of manufacturing flakes from a magnetic material having a preferred crystallite orientation, flakes and magnets manufactured therefrom.

摘要

A method of manufacturing flakes from hard magnetic material having a preferred orientation of crystallites is described, in which the cooling rate of a molten alloy which comprises a rare earth metal, iron and/or cobalt and boron is chosen to be so that the flakes have an average length of 10 mm and a thickness of between 10 and 70 mu m.
