Nedelkoski, Z, Kepaptsoglou, D, Lari, L et al. (8 more authors) (2017) Origin of reduced magnetization and domain formation in small magnetite nanoparticles. Scientific Reports, 7. 45997. ISSN 2045-2322
Abstract
The structural, chemical, and magnetic properties of magnetite nanoparticles are compared. Aberration corrected scanning transmission electron microscopy reveals the prevalence of antiphase boundaries in nanoparticles that have significantly reduced magnetization, relative to the bulk. Atomistic magnetic modelling of nanoparticles with and without these defects reveals the origin of the reduced moment. Strong antiferromagnetic interactions across antiphase boundaries support multiple magnetic domains even in particles as small as 12–14 nm.
