Structural, morphological and magnetic characters of PVP coated ZnFe2O4 nanoparticles

Abstract

The most stable and magnetic recoverable material XY2Z4 (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 ZnFe2O4 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 ZnFe2O4 nanoparticles are spherical in shape and has magnetic domain structure. The vibrating sample magnetometer (VSM) spectra indicated that the prepared ZnFe2O4 nanoparticles exhibited super paramagnetic behavior along with high saturation magnetization at room temperature. Such synthesis ZnFe2O4 nanoparticles with sympathetic size and tunable magnetic properties are used for various promising biomedical applications.
