Abstract

A new cross linked polymer compound (hydrogel) with fine Fe3O4-grains embedded in it has been investigated by neutron scattering. We studied the nanoscale structures of these ferrogels synthesized in a magnetic field and without a magnetic field. By means of polarized neutron scattering we studied the self-assembly of the particles under the influence of the magnetic field. Even in a weak field (H ∼ 65 Oe) the ferrogel showed strong spatial correlations of the particles; a strong field (H ∼ 4 kOe) induced slow growth of the interference effect. Over the observation time (several tens of hours) a cluster formation of particles was observed. This magnetic ordering is reversible: it disappears when switching off the external field.
