“…From Table 2 notice that the lattice parameter of CuAl (8.074-8.089 Å) is varied according to MF, but it matches with the previous work [13]. Besides the lattice parameter of CoF, MgF, and ZnF is slightly decreased compared to the literature [17][18][19][20], but the NiF is increasing comparable to Ref. [19].…”

“…742081 and 732410). The diffraction peaks are prominent and sharp, with only a small peak at around 32°, which may belong to hematite Fe 2 O 3 [ 28 , 29 , 30 ]. The intensity of the spinel phase’s primary peak decreases as the Mg content increases.…”

Using the auto combustion flash method, Ni1−x+2Mgx+2Fe2+3O4 (x = 0, 0.2, 0.6, 0.8 and 1) nano-ferrites were synthesized. All samples were thermally treated at 973 K for 3 h. The structural analysis for the synthesized samples was performed using XRD, high-resolution transmission electron microscopy (HRTEM), and FTIR. Scanning electron microscopy (SEM) was undertaken to explore the surface morphology of all the samples. The thermal stability of these samples was investigated using thermogravimetric analysis (TGA). XRD data show the presence of a single spinel phase for all the prepared samples. The intensity of the principal peak of the spinel phase decreases as Mg content increases, showing that Mg delays crystallinity. The Mg content raised the average grain size (D) from 0.084 μm to 0.1365 μm. TGA shows two stages of weight loss variation. The vibrating sample magnetometer (VSM) measurement shows that magnetic parameters, such as initial permeability (μi) and saturation magnetization (Ms), decay with rising Mg content. The permeability and magnetic anisotropy at different frequencies and temperatures were studied to show the samples’ magnetic behavior and determine the Curie temperature (TC), which depends on the internal structure. The electrical resistivity behavior shows the semi-conductivity trend of the samples. Finally, the dielectric constant increases sharply at high temperatures, explained by the increased mobility of charge carriers, and decreases with increasing frequency.

The multiferroic MF/CuAl2O4 (MF= CoFe2O4, NiFe2O4, MgFe2O4, and ZnFe2O4) was prepared using two stages of the sol-gel method. X-ray Diffraction (XRD), the Fourier transforms infrared absorption (FT-IR) and High-resolution Transmission Electron Microscope (HR-TEM) were used to examine the structure of all samples. From the XRD patterns, two standards of cubic spinels structure (CuAl2O4 + MF) were observed. The analysis of FTIR spectra confirmed the formation of the chemical and molecular structure changes in the MF/CuAl2O4. HR-TEM images showed a uniform particle distribution with a nanoscale of all samples. The magnetic properties were studied from the hysteresis loops using a vibrating sample magnetometer (VSM) and the magnetization M (T) by the Faraday balance method. All samples exhibited typical ferrimagnetic behavior, except for ZnF/CuAl recorded superparamagnetic. Curie temperature (TC) for all nanocomposites obtained from M(T) protocols, which is lower than the standard value of MF nanoferrites. The heating efficiency of all samples was investigated by measuring the Specific Absorption Rate (SAR) parameter. The SAR of NiF/CuAl showed a maximum value as well as saturation magnetization (Ms) and lowest coercivity (Hc) value.
