An investigation of the synthesis of the (Sm{sub 1-x}Y{sub x}){sub 5}Fe{sub 17} (x = 0 to 0.5) phase and its magnetic properties is presented. (Sm{sub 1-x}Y{sub x}){sub 5}Fe{sub 17} (x = 0 to 0.5) melt-spun ribbons that fully or mainly consisted of the amorphous phase and which showed low coercivity were prepared. Heat treatment of the melt-spun ribbons resulted in the formation of the (Sm,Y){sub 5}Fe{sub 17} phase. The highest remanence, 50 emu/g, was achieved in the annealed (Sm{sub 0.7}Y{sub 0.3}){sub 5}Fe{sub 17} melt-spun ribbon. However,the annealed (Sm{sub 1-x}Y{sub x}){sub 5}Fe{sub 17} (x = 0.4 to 0.5) melt-spun ribbons did not contain the (Sm,Y){sub 5}Fe{sub 17} phase and showed low coercivity values.
