We reported a systematic study of the effect of Zr content on the structural and magnetic properties of rapidly quenched Sm (CobalFe0.11Cu0.10Zrx)7 alloys with x varying from 0 to 0.04. The results show that the addition of Zr greatly affected the microstructure and magnetic properties of the heat-treated ribbons. The Zr-free ribbon had crystallized as the 1:7H structure as the main phase while the ribbon with Zr addition adopted the 2:17R structure type. A Sm2Co7 phase was observed in the heat-treated ribbons when the Zr content x increased to 0.04. It is found that while the Zr content was increased from 0 to 0.04, saturation magnetization of the heat-treated ribbons was decreased from 11.9kGs to 3.3 kGs, and the intrinsic coercivity was increased from 0.07 kOe to 11.7 kOe. The highest intrinsic coercivity, Hci=11.7 kOe, was obtained in the ribbon with Zr content of 0.03.
