Correlating the Crystalline Structure with Magnetic Morphology of Magnetic Nanoparticles
The objective of this proposal is to investigate the correlation of the magnetic morphology (using the SANSPOL) of differently shaped CoFe2O4 MNPs with their crystalline structure. SANSPOL measurements will enable us to precisely determine the chemical and magnetic morphology of MNPs with spatial resolution. The magnetization distribution through MNPs obtained by the investigation of the nuclear-magnetic interference term will unambiguously allow us to discriminate the bulk and surface contributions to the magnetic disorder. This will provide us relevant information to explain the connection between crystallinity and shape of the nanoparticles and their resulting magnetic morphology. The results of our combined approach will ultimately uncover the entanglement between the physical properties (magnetization and surface disorder) and the structure (i.e. crystalline shape and size). Revealing the correlation of the magnetic structure to the crystallinity and shape of nanoparticles is highly important for the explanation of relaxation effects, technologically relevant for e.g., magnetic hyperthermia, and the magnetic microstructure.
