Дана робота стосується відомого класу функціональних матеріялів, а саме, стрічковим аморфних металевих стопів на основі Fe та Co. Проаналізовано їхні магнетні властивості, зокрема особливості формування магнетної анізотропії, явища магнетної післядії (розбалансування), а також вплив на них термічних і термомагнетних оброблень. З’ясовано фізичну природу їхньої магнетної м’якости, роль локальних і макроскопічних магнетних анізотропій, магнетопружніх ефектів, магнетострикції та доменної структури у формуванні петлі перемагнетування. Зазначено основні джерела їхньої магнетної анізотропії, серед яких визначальну роль відіграє магнетопружня анізотропія, зумовлена внутрішніми напруженнями та магнетострикцією, а також анізотропія направленого впорядкування атомових пар. Окрім того, наведена магнетна анізотропія є термічно активованим процесом, рушійною силою якого виступає міжатомова магнетна взаємодія, а ефективність її формування зростає зі зменшенням магнетострикції стопу. Представлено механізми наведення одновісної анізотропії під час відпалу в магнетному полі та термомеханічного оброблення, а також вплив їх на коерцитивну силу, магнетну проникність і втрати на перемагнетування. Визначено, що температурні та часові нестабільності їхніх магнетних властивостей пов’язані зі стабілізацією меж доменів через направлене атомове впорядкування, а дослідження їх відбувається за допомогою розбалансування. Показано перспективність використання аморфних магнетом’яких матеріялів із нульовою магнетострикцією в сучасних середньо- та високочастотних електромагнетних пристроях.

Ключові слова: аморфна металева стрічка, магнетні властивості, термічне та термомагнетне оброблення, магнетна анізотропія, розбалансування.
