Neutron investigations of ferrofluids

Abstract

A review of neutron scattering researches of various magnetic fluids (ferrofluids) is made. Advantages and disadvantages of other complementary methods for the structure characterization of ferrofluids are discussed. The small-angle neutron scattering (SANS) method with a wavelength of 0.1–1 nm is a classic example of applying radiation to the determination of a structure in liquid nanosystems on a scale of 1–100 nm. The capabilities of the SANS method for the analysis of a magnetic fluid structure are illustrated by real examples.
