Structural, morphological and magnetic characters of PVP coated ZnFe2O4 nanoparticles

The most stable and magnetic recoverable material XY 2 Z 4 (X = Zn, Y = Fe and Z = O) having spinel ferrite nanoparticles were synthesized by chemical co-precipitation technique using polyvinyl pyrrolidone (PVP) as the surfactant. The synthesized nanoparticles were characterized by using various characterization techniques. The X-ray diffraction (XRD) analyses revealed that, the ZnFe 2 O 4 have normal spinel structure of phase pure polycrystalline in nature. The FT-IR analysis revealed that the two prestigious vibration bands recorded near (540–550 cm −1 ) and (455–470 cm −1 ) show the presence of tetrahedral and octahedral voids in zinc ferrite. The transmission electron microscopy (TEM) photographs showed the synthesized ZnFe 2 O 4 nanoparticles are spherical in shape and has magnetic domain structure. The vibrating sample magnetometer (VSM) spectra indicated that the prepared ZnFe 2 O 4 nanoparticles exhibited super paramagnetic behavior along with high saturation magnetization at room temperature. Such synthesis ZnFe 2 O 4 nanoparticles with sympathetic size and tunable magnetic properties are used for various promising biomedical applications.
