Исследовано влияние термобарической обработки (P = 7 GPa, T = 2300° С) на растворимость меди и цинка в Mn 1+x Sb со структурой никель-арсенидного типа. Показано, что P-T-обработка приводит к увеличению растворимости меди в антимониде марганца со структурой типа арсенида никеля (не более 30 at.%) и не повышает растворимость цинка. Рост содержания меди существенно меняет магнитные характеристики (удельную намагниченность, температуру Кюри) сплавов по сравнению с характеристиками незамещенного антимонида марганца Mn 1.48 Fe 0.02 Sb. The influence of hot-pressing treatment (P = 7 GPa, T = 2300°С) on Cu and Zn solubility in Mn 1+x Sb with the NiAs-type crystal structure has been investigated. It was shown that the P-T processing leads to the increase of copper solubility in Mn 1+x Sb with the NiAs- type crystal structure (not more than 30 at.%) and does not influence the zinc solubility. The increase of copper solubility leads to changes in magnetic characteristics of solid solution (e.g., specific magnetization, Curie point) as compared to those of unsubstituted Mn 1.48 Fe 0.02 Sb.
