Магнитные Свойства Прессованных Нанопорошков Гексаферрита Бария

Abstract

Magnetic force microscopy and magnetometry were used to study the magnetic characteristics of pressed nanosized powders BaFe12O19. The powders were obtained by chemical coprecipitation. Magnetic anisotropy of the “easy-plane” type, formed after the pressing operation, was found. The nature of the appearance of anisotropy is discussed.
