Dispersible cobalt chromite nanoparticles: facile synthesis and size driven collapse of magnetism

Popis výsledku v původním jazyce

In our work, we focused on preparation of standalone cobalt chromite nanoparticles (NPs). We introduced hydrothermal decomposition of cobalt(II)/chromium(III) oleates in water/ethanol system without need of additional thermal treatment, which lead to stable cobalt chromite nanoparticles with diameter of 3.0(1) – 4.2(1) nm. The as-prepared NPs are coated with covalently bonded oleic acid and can be easily dispersed in non-polar solvents, which makes them excellent candidates for custom surface modifications. The NPs were studied using large number of characterization techniques: powder x-ray diffraction, transmission electron microscopy, small-angle x-ray scattering, and vibrational spectroscopies. The uniform cobalt chromite NPs coated with oleic acid with size of 3 - 4 nm are excellent prototypes for studying the size effect on magnetic (and feroic), and can be subjected to manifold surface functionalization required for their embedding in smart nanostructures and nanocomposites.
