摘要：

Ferrite particles with 10% Mn substitution in Fe3O4 are synthesized. These particles are used to prepare kerosene based magnetic fluid. Detailed characteristics of these particles are studied by X-ray, SAXS, EM, magnetization and Mossbauer techniques. Magnetization measurements at 4.2 K suggest the presence of canting on the surface layer. This was further confirmed by Mossbauer measurements. The anisotropy constant of the particle was calculated using the temperature decay of remanence. Particle size distribution determined by SAXS, SANS, EM and magnetization measurements are well in agreement.
