Золь-гель синтез, кристаллическая структура и магнитные свойства нанокристаллического ортоферрита празеодима
Аннотация
В работе описан процесс получения нанокристаллического ортоферрита празеодима методом золь-гель синтеза с использованием водного раствора метанола в качестве сорастворителя. Однофазные нанокристаллы PrFeO3 формировались путём отжига прекурсора при температурах 650, 750, 850 и 950 °C в течение 60 минут. Размер кристаллов, объём элементарной ячейки и коэрцитивная сила (Hc) нанокристаллического PrFeO3 возрастают по мере увеличения температуры отжига. Полученный ортоферрит празеодима демонстрирует парамагнитные свойства при Hc = 28 – 34 Oe.
