John J Croat: High energy product rare earth-iron magnet alloys. General Motors Corporation, Elizabeth F Harasek, July 25, 1989: US04851058 (35 worldwide citation)

The hard magnetic properties, including intrinsic coercivity, remanence and energy product of rapidly quenched, rare earth-transition metal alloys has been substantially increased by the addition of suitable amounts of the element boron. The preferred rare earth constituent elements are neodymium an ...
