Abstract

We have performed small-angle polarized-neutron scattering from ultra-fine ZnFe2O4 particles to confirm the intraparticle magnetic structure, which has been considered the origin of its peculiar magnetic features. On the basis of the Q-dependent differential neutron-scattering intensity, we were unable to detect any magnetic structure consisting of magnetically inactive surface layer with magnetic core. Thus, the magnetic behavior of ultra-fine ZnFe2O4 particles is explained in terms of a deviation in cation distribution from the normal spinel structure.
