Unmasking the Complex Core-Multishell Morphology of Magnetic Nanoparticles
This proposal aims to investigate the correlation of the chemical and magnetic morphology of ¿-Fe3N magnetic nanoparticles (MNPs) encapsulated in SiO2 with a complicated organic bridge (using the SANSPOL) with their macroscopic performance. SANSPOL measurements will enable us to precisely determine very complex chemical morphology and, furthermore, to unveil the magnetization distribution of MNPs with spatial resolution. A possible formed oxidic layer at the MNPs surface can be revealed solely by SANSPOL due to the enhanced scattering contrast not achievable by X-rays. Moreover, by investigating the nuclear-magnetic interference term will unambiguously allow us to disentangle the core and oxidic shell magnetization contributions to the total magnetization and reveal the possible presence of surface effects (spin disorder or canting). This study will ultimately uncover the connection between the physical properties (magnetization and surface disorder) and the complex core-multishell structure highly desirable for the explanation of the macroscopic performance of ¿-Fe3N MNPs in MRI, MPI, and magnetic hyperthermia.
