The coercivity {ital H}{sub {ital ci}} of melt-spun Sm-Fe-Ti alloys can be increased to above 4.0 kA/cm by the addition of Zr and Co. Co-substitutions also enhance the remanence {ital J}{sub {ital r}} and suppress the formation of {alpha}-Fe, both of which result in a high-energy product, ({ital BH}){sub max}, of up to 56 kJ/m{sup 3}, the highest value reported so far for 1:12-type magnets. In Sm{sub 20}Fe{sub 70}Ti{sub 10} alloys prepared by mechanical alloying or by rapid quenching a new hard-magnetic phase is observed with room-temperature coercivities of 40 and 33 kA/cm, respectively.
