摘要：
The dependence of remanence enhancement of nanocomposite permanent magnetic alloy ribbons of Pr2Fe14B/α-Fe on volume fraction of alpha-fe phase, average grain size (d), wheel speed, and the ribbon thickness has been investigated. The results show that the remanence enhancement of nanocomposite permanent magnetic alloy ribbon of Pr2Fe14 B/alpha-Fe is related to the volume fraction of alpha-Fe and the average grain size. When the content of alpha-Fe(volume fraction) is 30%, the alloy appears maximum remanence enhancement. Based on the analysis of initial magnetization curves, and the relationship between Hci and Hext, the model of nucleation field of reversed domain and exchange coupling pinning field has been proposed, and the mechanism of magnetic hardening of the composite materials has been discussed.
