PURPOSE:To prevent efflorescent phenomenon by adding Ag and Au to CaCu5-type permanent magnet consisting of La-containing REM and Co. CONSTITUTION:An alloy in which part of M of the RMA alloy is replaced with T and 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 Ag and Au, and 3.6<=A<=7.5). |
