Structure of hybrid ferrofluidic dispersions by polarized SANS
With the aim to enhance the magnetic, optical, and dynamic properties, conventional ferrofluids (consisting of spherical magnetic nanoparticles - maghemite and cobalt ferrite) are doped with anisometric nanoparticles (hematite nanospindles and nickel nanorods) resulting in so-called hybrid ferrofluids. The main objective of this proposal is the detailed study of the structural and magnetic morphology of arrangements of spherical magnetic particles around elongated nanoparticles in hybrid ferrofluidic dispersions using polarized SANS (SANSPOL). Furthermore, we intend to investigate the reorientation behaviour of the aggregate system with respect to the elongated particle scaffold as function of the external magnetic field. These information on the microstructure evolution will give important information in order to explain the macroscopic behavior of hybrid ferrofluidic dispersions.
