A stable metal ferrite Construction, physical Characterizations, and investigation magnetic properties in thin polymer films

A stable nickel ferrite (NiFe₂O₄) was constructed as incorporated into starch grafted acrylic acid copolymer matrix by co-precipitations followed by annealing. A sample, as annealed at temperature 600 °C, yields a NiFe₂O₄ of tailored the magnetic properties. The structural, morphological and magnetic properties were investigated by XRD, FTIR, SEM and VSM characterizations. SEM and XRD analysis indicate that particle size in the nano range. In-situ polymerization process was used to insert prepared material with acceptable surface morphology into a starch-grafted methyl methacrylate copolymer. By using FTIR and VSM to assess the magnetic characteristics, nanocomposite was created in this manner was evaluated. Magnetic properties of (NiFe₂O₄) arise with saturation magnetization M_s = 19 emµg⁻¹. Studies made at room temperature reveals the soft nature of synthesized ferrites. These approaches outcomes demonstrated the material value as a biodegradable thin film with tunable magnetic characteristics that may be used as magnetic strips in future.
