Abstract: Abstract As-sintered multi-main-phase Nd-Ce-Fe-B permanent magnets typically exhibit a higher coercivity than as-sintered single-main-phase Nd-Ce-Fe-B magnets with identical content of Ce. To clarify the microstructural features that are relevant to the coercivity, as-sintered multi-main-phase Nd-Ce-Fe-B… read more here.

Abstract: Abstract Massive rare earth oxides inevitably form at high La-Ce substitution, causing inadequate liquid-phase-sintering, direct exchange coupling of ferromagnetic grains, obscure core-shell morphology and severe coercivity degradation of multi-main-phase (MMP) Nd-La-Ce-Fe-B sintered magnets. To fully… read more here.

Abstract: Nd2Fe14B have attracted intensive attentions due to its excellent magnetic properties since 1980s. However, large demands for the expensive rare earth (mainly refers to Nd/Pr/Dy) limit its wider applications. Investigations of Ce-doped Nd2Fe14B have been… read more here.
