Magnetic Core-Shell Morphology in Cobalt-Doped Iron Oxide Nanoparticles of Different Sizes
The objective of this proposal is to investigate the spatial resolved magnetization behavior in cobalt-doped iron oxide NPs during oxidation. The samples of this proposal were synthesized out of a mixed iron-cobalt-oleate precursor following a thermal decomposition route. The particle size is precisely controlled by variation of heating rates. For this synthesis pathway, formation of a core-shell morphology is known, consisting of a wustite core which topotaxially oxidizes to maghemite near the particle surface. We want to analyze these highly interesting materials after partly the oxidation process takes place by using magnetic SANS to elucidate the quantitative magnetization independently in particle core and shell to compare with the same samples, which were measured in the early stage of topotaxial oxidation at ISIS facility in February.
