PURPOSE:To prevent efflorescent phenomenon by adding S, P, Sb, and Bi to CaCu5-type permanent magnet consisting of La-containing REM and Co. CONSTITUTION:A permanent magnet in which part of M of the RMA alloy is replaced with T and the T/La atomic ratio is in the relationship 0.01<=T/La<=1. (where R is La or a combination of La and one or two more of Sm, Ce, Pr, Nb, Y, and Gd, M is Co or a combination of Co and one or two more of Mn, Fe, Cu, and Ni, T is one or a combination of two or more of S, P, Sb, and Bi, and 3.6<=A<= 7.5). |
