    • Abstract

       

      This article reviews the work carried out at Trombay in a variety of single and mixed spinel ferrites. The use of polarised neutrons in the elucidation of cation distribution and magnetic structures in powder specimens is emphasised. Magnetic form factor studies in single crystal specimens of Fe3O4 and MnFe2O4 are described. Evaluation of dominant exchange interactions in a few powder specimens in their paramagnetic phase using the cold neutron scattering technique is described. Measurements of the acoustic magnon dispersion in MnFe2O4 and Li0.13Fe2.87O4 are outlined.
