Role of Coupling Divalent Metal Ion of Tin on Structural and Magnetic Properties of NiFe2O4 Nanoparticles

摘要

In this research article, we report the role of coupling divalent metal ion tin (Sn) on the structural and magnetic properties of NiFe2O4 nanoparticles (NPs). A series of nanocrystalline nickel ferrites [Ni(1-x)Sn(x)Fe2O4] with composition x = 0.0, 0.2, 0.4, 0.6, and 0.8 are synthesized by coprecipitation method. The synthesized title product is subjected to a variety of analytical techniques such as powder X-ray diffractometer (PXRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM), to understand the structural and magnetic properties. PXRD patterns confirm the single-phase formation of NiFe2O4 NPs as well as Sn concentration. SEM images showed the surface morphology details and size of the particles. VSM studies reveal that the saturation magnetization (M-s) of soft superparamagnetic nature reduces with the variation of Sn concentration.
