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