PURPOSE:To improve thermal stability using an inexpensive element instead of Ga, and also to improve the close adhesiveness between the base layer Cu and plating. CONSTITUTION:This permanent magnet consists of the composition of (Nd1-x-y-zCexPryDyz)aFebCocBdZneCufMgAlho (in the form of 0.001<=X<=0.1, 0.05<=Y<=0.5, 0.001<=Z<=0.25, M indicates at least a kind selected from V, Mo, Nb and W, 5<=a<=18wt.%, 65<=b<=85wt.%, 0<=c<=20wt.%, 4<=d<=15wt.%, 0<=e<=7wt.%, 0<=f<=7wt.%, 0<=g<=5wt.% and 0<=h<=2wt.%). |
