摘要：

The magnetic phase diagram for the system Cfmm2Fe14-xCoxB, where Cfmm stands for Ce-free mischmetal, was determined. These systems were found to possess T(SR1)'s lower than their Nd counterparts. This is directly attributable to the fact that Ce-free mischmetal contains both La, which tends to dilute the anisotropy of the Nd, and Pr, which exhibits axial anisotropy. Those systems rich in Co (x greater-than-or-equal-to 10) were found to exhibit two spin reorientations, a type 1 spin reorientation at low temperature, characteristic of the Nd in the Ce-free mischmetal, and a type 2 spin reorientation at higher temperatures, resulting from the competing anisotropies of the rare earth and transition metal sublattices.
