Preparation and magnetic studies of nickel ferrite nanoparticles substituted by Sn super(4+) and Cu super(2+)

The mixed ferrite systems, namely NiFe sub(2-2x)Sn sub(x)Cu sub(x)O sub(4) (x=0, 0.1, 0.2, and 0.3) nanoparticles have been studied to understand their structural and magnetic parameters. The NiFe sub(2-2x)Sn sub(x)Cu sub(x)O sub(4) nanoparticles were prepared by high energy ball milling (HEBM). The...

Description
Summary:The mixed ferrite systems, namely NiFe sub(2-2x)Sn sub(x)Cu sub(x)O sub(4) (x=0, 0.1, 0.2, and 0.3) nanoparticles have been studied to understand their structural and magnetic parameters. The NiFe sub(2-2x)Sn sub(x)Cu sub(x)O sub(4) nanoparticles were prepared by high energy ball milling (HEBM). The samples were characterized by the X-ray diffraction technique. All samples exhibited spinel structures. The crystalline size and internal strain were evaluated by XRD patterns using Williamson-Hall and Scherrer methods. Magnetic properties of the nanoparticles ferrite were studied by means of alternating gradient force magnetometry (AGFM) and Faraday balance.
