摘要: Nanometer size NiFe2O4 particles were synthesized by the Citrate precursor technique and control of solid state reactivity yields monophasic ultrafine which characterized XRD, SEM BET surface area measurements. Interestingly, single domain found to form linear chain like clusters because strong magnetic dipolar interactions. The low saturation magnetization values attributed spin noncollinearity predominantly at surface. Hopkinson effect is exhibited an assembly noninteracting explained within mathematical formalism given Stoner Wohlfarth model.
