An intrinsic room-temperature coercivity of 7.45 kOe has been found in melt-spun Nd/sub 0.4/Fe/sub 0.6/; this value is the largest ever reported for a rare-earth--iron alloy. A significant correlation was found between quench rate and coercivitiy, suggesting that the quenched alloys consist of fine crystallites or clusters, whose average particle size can be matched to the single-domain optimum by the appropriate quench rate.
