Abstract
Small-angle neutron scattering (SANS) is a powerful technique for studying the microstructure of ferrofluids under different conditions. The paper reviews recent results obtained from the analysis of SANS data for a number of ferrofluids based on non-polar and polar carriers. Specific features revealed by SANS and their comparison for different types of ferrofluids are discussed. Problems to be solved are emphasized. Tables 2, Figs 4, Refs 34.
