By appropriate variation of starting composition we demonstrate that melt-spun materials comprised primarily of Nd2(CoxFe1−x)14B and having optimum energy products can be prepared. Twelve cobalt concentrations spanning the entire cobalt substitution range have been investigated. We report ambient as well as elevated temperature magnetic properties. A spin reorientation characterized by a change of easy magnetization direction from the c axis to the basal plane of the Nd2Fe14B structure occurs at a temperature Ts for x≳0.65. In that concentration range the technological properties are limited by Ts rather than the Curie temperature Tc.
