Microstructure and magnetic properties of rapidly solidified Sm(CobalFe0.11Cu0.10Zrx)7 alloys

摘要：

Effects of Zr content on the structural,morphological,and magnetic properties of rapidly quenched Sm(CoFe0.11Cu0.10Zrx)7 (x=0.0.04) alloys were investigated.The Zr-free ribbon crystallizes with the 1:H structure as a major phase while the ribbons with Zr addition adopts the 2:7R 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.
