【 摘 要 】
The hydrothermal synthesis of Fe3O4nanoparticles (NPs) (3/ FeCl2precursor solution at pH ∼ 12 has been confirmed using complementary characterisation techniques of transmission electron microscopy and X-ray diffractometry. Off-axis electron holography allowed for visualisation of their single domain (SD) nature, as well as inter-particle interactions, with the latter attributed to explain the pseudo-SD/multi-domain behaviour demonstrated by bulk magnetic measurements.
