Abstract: “The magnetic magnesium ferrite (MgFe₂O₄) with a partially inverse spinel structure has been prepared by the classic ceramic method, which have practical application in information storage systems, magnetocaloric refrigeration and magnetic diagnostics. Nickel-magnesium ferrites (Ni:MgxFe_3-xO₄ or Mg(1-x)NixFe2O4; 0 ≤ x < 1) are magnetic materials of technological significance due to low electrical conductivity, low magnetic coercivity and low eddy current deceives. Magnesium plays an important role in the electrical and magnetic properties of Mg_(1-x)Ni_xFe₂O₄. Thin films were synthesized on different substrates with Spray Pyrolysis (SP) technique. The thin films were analyzed through Atomic Force Microscopy (AFM), X-ray Diffraction (XRD) and UV–Vis double beam spectrophotometer and for magnetic properties of films were used Vibrating-sample magnetometer (VSM) technique. In this study, the film is doped with material having magnetic properties and non-magnetic material. The change in the magnetic properties of the film will be examined as a result of the doping. As a result, the magnetic hysteresis curve of the film was changed by doping. Investigation of magnetic properties is very important for magnetic device applications such as magnetic recording, in magnetic sensor technology and room temperature giant magnetoresistance (GMR) applications.“
