摘要：

Magnetic small-angle scattering of non-polarized and polarized neutrons from ferrofluds (magnetite covered by oleic acid in benzene) is analyzed. A complex correlation in the magnetic structure is observed. It takes place at the length of more than the particle size, and has a core-shell-like organization. Along with it no spatial interparticle correlation in the nuclear structure is detected. (C) 2003 Elsevier B.V. All rights reserved.
