Abstract

The work studies sintered materials for aviation navigation devices based on praseodymium with an impurity of neodymium. It has been established that at a high content of cobalt, which is necessary to increase the temperature stability, the impurity of neodymium is acceptable only in minimal quantities. In neodymium-based materials, the content of the main magnetic phase R2(Fe, Co)14B decreases sharply with an increase in the content of cobalt. It had been established that a material with a minimum content of cerium has optimal magnetic properties.
