ε-Fe2O3: An Advanced Nanomaterial Exhibiting Giant Coercive Field, Millimeter-Wave Ferromagnetic Resonance, and Magnetoelectric Coupling

Abstract: Nanosized iron oxides still attract significant attention within the scientific community, because of their application-promising properties. Among them, ε-Fe 2 O 3 constitutes a remarkable phase, taking pride in a giant coercive field at room temperature, significant ferromagnetic resonance, and coupled magnetoelectric features that are not observed in any other simple metal oxide phase. In this work, we review basic structural and magnetic characteristics of this extraordinary nanomaterial with an emphasis o… Show more

“…Установлена связь между магнитной вязкостью и магнитным шумом, вызванным случайными термически индуцированными перемагничиваниями отдельных наночастиц. [7]. Несмот-ря на интенсивные исследования этого соединения, вопросы о спект-ре магнитных флуктуаций, механизмах спонтанного размагничивания, временной стабильности и специфике термоактивационных процессов А.И.…”

“…The main problem is the difficulties with its synthesis. It is known that this phase is thermally unstable (converts to hematite at temperatures about 750 °C) and can exist only in nanodispersed state (also converts to hematite when interacts with other particles due to low surface energy) [10].…”
