Abstract
High isotropic remanences and energy products have been obtained in melt-spun Nd-Fe-B samples with a fine grained mixture of α-Fe and Nd2Fe14B1 containing more than 50 wt % of α-Fe. Reduced remanences as high as 0.78 with high saturation magnetization (190 emu/g) led to (BH)max of 14 MGOe. The coercivities varied from 2–4 kOe for samples with 70–50 wt % α-Fe, respectively. Reversible demagnetization curves were observed consistent with the ‘‘exchange spring’’ mechanism.This publication has 6 references indexed in Scilit:
