摘要：

The concentration and temperature dependencies of magnetic anisotropy in the quasitemary (Y1-xThx)(2)Fe14B system have been studied on aligned powders. With increasing Th content, the enhancement of the uniaxial anisotropy at low temperatures (K-1 at 4.2 K increases from 0.8 MJ m(-3) for x=0 to 1.5 MJ m(-3) for x=1) and the change in K-1(T) behaviour from anomalous characteristic for Y,Fe,,B to the monotonous decrease with increasing temperature have been found.
