Дана робота стосується особливого класу функціональних матеріялів — магнетом’яких стопів і композитів на їхній основі. Розглянуто їхні головні переваги та недоліки. Приділено особливу увагу порошковим магнетом’яким композитам, що являють собою зв’язану в єдиний конґломерат суміш феромагнетного порошку та зв’язки (діелектрика), де кожну частинку порошку оточено зв’язкою, що утворює неперервну діелектричну фазу. Визначено основні чинники впливу на властивості порошкових магнетом’яких композитів: вибір феромагнетика з потрібними магнетними властивостями, використання частинок порошку потрібного розміру та форми, застосування певного типу ізолятора та методу його нанесення, вибір умов пресування й оптимальний режим термічного оброблення. Показано, що основний спосіб формування магнетодіелектриків ґрунтується на методах порошкової металурґії. Технологічний процес одержання магнетодіелектриків включає: підготовку феромагнетного порошку, змішування його зі зв’язувальним, пресування, термооброблення, механічне оброблення, нанесення захисного покриття та вихідний контроль властивостей.

Ключові слова: магнетні матеріяли, магнетом’які композити, коерцитивна сила, магнетодіелектрик, магнетопровід.
