| 摘 要： | Effects of Zr content on the structural, morphological, and magnetic properties of rapidly quenched Sm（CoF0.11CU0.10Zrx）7 （x=0 0.04） alloys were investigated. The Zr-free ribbon crystallizes with the 2：17H structure as a major phase while the ribbons with Zr addition adopts the 2：17R structure type. The ribbons with x-0.03 exhibits a highest coercivity, Hci=933.7 kA/m, because a smaller uniform cellular structure along with a lamellar phase is formed. The decrease of Hci above x〉0.03 is mainly related to the formation of 2：7 phase.
