PURPOSE:To prevent efflorescent phenomenon by adding Na, Li, Mg, and Ca to CaCu5-type permanent magnet consisting of La-constaining REM and Co. CONSTITUTION:An alloy 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 or more of Sm, Ce, Pr, Nd, Y, and Gd, M is Co or a combination of Co and one or two or more of Mn, Fe, Cu, and Ni, T is one or a combination of two or more of Li, Na, Mg, and Ca, and 3.6<=A<=7.5). |
