Abstract An investigation of the synthesis of the YCo2Fe2B-type phase and its magnetic properties is presented. As-rapidly quenched specimens produced from YCo2Fe2B alloy were amorphous and did not show high coercivity. A specimen with the YCo2Fe2B phase was obtained by annealing of the amorphous specimen. The specimen had a Curie temperature of 610 K but did not show high coercivity. When Y0.75Sm0.25Co2Fe2B alloy was used, a specimen with the (Y,Sm)Co2Fe2B phase was obtained by annealing of the as-rapidly quenched amorphous specimen. The resultant specimen exhibited a high coercivity of 8.90 kOe with a Curie temperature of 630 K.
