Synthesis of nanocrystalline NiCoMn ferrite and investigation their physical properties

Abstract

Nickel Ferrites nanoparticles doped with cobalt and manganese (Ni0.99Co0.01Mn0.01Fe1.99O4) were synthesized by sol–gel combustion method. The effect of calcination temperature on the properties of the ferrite was also studied. The structural properties of all samples investigated using X-ray diffraction technique. The XRD analysis indicated that the all samples have cubic spinel structure. Their M(H) loops have been traced using a Vibrating Sample Magnetometer (VSM). The saturation magnetization (Ms) was increased as the calcination temperature increased.
