“…Magnesium ferrite is used in heterogeneous catalysis, adsorption, sensors, and magnetic technologies (1)(2)(3)(4) . The non-magnetic Cu resides in a tetrahedral (A) site whose doping can modify the structural, electrical, and magnetic properties (5)(6)(7) . Doping of Al (8,9) , Ge (10) , Cu (11) , Ni (12) , Cr (13) , Sm-Gd (14) , Ce-Gd (15) on magnesium ferrite and their effects on the electrical, dielectric and magnetic properties were studied (16)(17)(18) .…”

Objective: To prepare Cu doped Mg 0.5−x Cu x Zn 0.5 Fe 2 O 4 (x = 0.0, 0.05, 0.1, 0.15, 0.2 and 0.25) spinel ferrites materials and study the structure, morphology, and magnetic properties. Methods: Cu doped Mg-Zn spinel ferrites are magnetic and highly resistive materials. They were synthesized by the method of solid-state reaction and characterized by x-ray diffraction (XRD), field effect scanning electron microscopy (FESEM), Fourier transform infrared (FTIR), and vibrating sample magnetometer (VSM) for their structural, compositional, morphological, functional properties. They are with spinel structure under Fd-3m space group. Their crystallite size was 44.58 nm to 31.02 nm range after calcined at 1000 o C. Their spinel structure was confirmed with FT-IR analysis, whose absorption bands were 598.84 -580.40 cm -1 and 405.35 -402.15 cm -1 range for higher and lower frequency, respectively. The value of coercivity is in the range 146.33 -9.427 Oe with the variation of content. The lower values of the coercivity indicated the soft ferrimagnetic nature of the synthesized materials. Findings/ Application: Substitution of non-magnetic Cu 2+ ions strongly influenced the structural and magnetic properties of magnesium ferrites.
