摘要：

Nanoparticles of cobalt ferrite were synthesized by two different surfactants cetyl trimethyl ammonium bromide (CTAB) and sodium dodecyl sulphate (SDS) by the microemulsion method. Formation of cobalt ferrite was confirmed by structural characterization techniques XRD and TEM. The magnetic properties of these systems were studied using Mossbauer spectroscopy and SQUID magnetometry. The study determined the impact of the synthetic procedure and surfactant composition on the nanomaterial characteristics. The overall magnetic response for the material was different compared to the bulk with a major decrease in room temperature magnetic saturation. Magnetic properties were affected by the type of surfactant template due to its impact on the geometry of the synthesized cobalt ferrite nanoparticles.
