Ribbons with a composition of Sm(Co,Fe,Cu,Zr)7.4 have been prepared by the melt-spinning technique, to examine their magnetic properties and structures. In the as-prepared state, the ribbon specimens are composed of a single phase with a very low coercivity. With appropriate heat treatments, however, the specimen is transformed into a two-phase structure in which a celullar structure of 2-17 phase is divided by boundaries of 1-5 phase. As a result, the maximum value, 460 kA/m, may be achieved. These results obtained for the melt-spun ribbons are very similar to those for the sintered magnet alloy of the same composition.
