Description

The formation of metastable (TM)5Sm and (TM)7Sm2 (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 (Fe/sub 1-//sub x/ Co/sub x/)5Sm and (Fe/sub 1-//sub x/ Co/sub x/)7Sm2 (0≤x≤1.0) alloys. The (Fe/sub 1-//sub x/ Co/sub 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
