- Abstract
CoLa0.1Fe1.9O4 ferrite nanocrystal was synthesized under an induced AC magnetic field by the emulsion method. From XRD pattern, it is shown that all the samples are cubic structure of the spinel ferrite. The morphology of samples synthesized under an induced AC magnetic field was flake-like in shape from TEM image. Both the strength and acting time of external magnetic field influence the crystallite sizes of samples. Magnetic properties of samples were measured by vibrating samples magnetometer (VSM). The changing morphology of sample when an external magnetic field was applied, which might be responsible for the low magnetic properties.
