    Abstract

    The formation of metastable (TM)5Sm and (TM)7Sm 2 (TM=Fe-Co) compounds and their magnetic properties have been investigatyed by the x-ray diffraction method and analysis of thermomagnetization curves for rapidly quenched (Fe1-x Co x)5Sm and (Fe1-x Cox) 7Sm2 (0≤x≤1.0) alloys. The (Fe1-x Co x)5Sm compound is formed with a single phase in the range 0.7≤x≤1.0 and a mixture with other stable compounds in other composition range. On the other hand, the metastable (TM)7Sm2 compound exists in the mixed state with a large amount of (TM)3Sm stable compound in the range 0.7≤x≤1.0. The single phase (RM)5Sm compound exhibits a huge coercivity of 5-14 kOe.
