Abstract

Was investigated by the effect of using yttrium on the properties of the sintered Magnets Nd–Dy–Y–Fe–Co–B. It is shown that the coercive force on the magnetization and induction is decreased with an increase in the content of yttrium. The magnitude of the rectangulation of the clarification curve slightly increases. The value of residual induction and the magnetization of saturation changes not significantly, but tend to increase with the content of yttria. Thus yttrium is not desirable impurity in thermostable magnets for navigation instruments.
