Abstract: The electronic structures of a (001) surface of crystalline [Nd.ub.2][Fe.sub.14]B are studied by using a slab model and the crystal field parameters are estimated at Nd sites based on site principles calculations. The results have shown that Nd ions located around the (001) surfaces of crystalline [Nd.sub.2][Fe.sub.14]B would be nucleation sites of reversed magnetic domains.
