摘要: A permanent magnet is provided which retains its magnetic properties and exhibits a linear extrinsic demagnetization curve at elevated temperatures up to 700° C. The magnet is represented by the general formula RE(CowFevCuxTy)z, where RE is a rare earth metal selected from the group consisting of Sm, Gd, Pr, Nd, Dy, Ce, Ho, Er, La, Y, Th, and mixtures thereof and T represents a transition metal(s) selected from the group consisting of Zr, Hf, Ti, Mn, Cr, Nb, Mo, W, V, Ni, Ta, and mixtures thereof.
摘要翻译: 提供永磁体,其保持其磁特性并且在高达700℃的升高的温度下表现出线性的外在退磁曲线。磁体由通式RE(CowFevCuxTy)z表示,其中RE是选自 由Sm,Gd,Pr,Nd,Dy,Ce,Ho,Er,La,Y,Th及其混合物组成的组,T表示选自Zr,Hf,Ti,Mn ,Cr,Nb,Mo,W,V,Ni,Ta及其混合物。

摘要: A permanent magnet is provided which retains its magnetic properties and exhibits a linear extrinsic demagnetization curve at elevated temperatures up to 700° C. The magnet is represented by the general formula RE(CoWFeVCuXTY)Z, where RE is a rare earth metal selected from the group consisting of Sm, Gd, Pr, Nd, Dy, Ce, Ho, Er, La, Y, Tb, and mixtures thereof and T represents a transition metal(s) selected from the group consisting of Zr, Hf, Ti, Mn, Cr, Nb, Mo, W, V, Ni, Ta, and mixtures thereof.
