В огляді наводяться експериментальні результати, одержані під час дослідження твердофазної реакції впорядкування A1→L10 у нанорозмірних плівках FePd і FePt еквіатомного складу, а також леґованих Ag, Au під час відпалу у вакуумі та водні. Розглянуто поведінку Гідроґену в плівці та його вплив на фазовий склад, структуру, а також викликану Гідроґеном зміну магнетних станів і властивостей. Процеси впорядкування у плівках на основі еквіатомних стопів FePd і FePt пришвидшуються під час відпалу у середовищі водню порівняно з відпалення у вакуумі. Введення атомів H спричинює зміну електронної структури, магнетних властивостей і станів плівки на основі FePd. Показано оборотні зміни магнетних станів плівки FePd: феромагнетик↔парамагнетик шляхом зміни температури та часу відпалу плівки у середовищі водню. Динаміку структурних змін у плівках FePd під час процесів упорядкування досліджено Рамановою спектроскопією.

Ключові слова: водень, відпал, упорядкування, L10-FePd, L10-FePt, магнетні властивості, магнетотвердий стан, парамагнетний стан, коерцитивна сила, феромагнетний резонанс, Раманова спектроскопія.
