Investigation of annealing effects on the physical properties of Ni_0.6Zn_0.4Fe_1.5Al_0.5O₄ ferrite

Abstract

In the present study, the structural, morphological, electrical, and dielectric properties of Ni0.6Zn0.4Fe1.5Al0.5O4 annealed at 600 °C, 900 °C, and 1200 °C were investigated.

Investigation of the structural, optical, elastic and electrical properties of spinel LiZn2Fe3O8 nanoparticles annealed at two distinct temperatures

“…More details in the Rietveld analyses have been reported in our previous work. 18 Fitting parameters were found to be comparable to those of similar spinel ferrite samples. 18,19 The unit cell parameters and atomic positions along with the AO 6 octahedral and BO 4 tetrahedral sites of the Li-Zn ferrite are shown in the inset of Fig.…”

Magnetic and spectroscopic properties of Ni–Zn–Al ferrite spinel: from the nanoscale to microscale

“…The process was described in detail elsewhere. 23 In a typical preparation, analytical purity grade Fe(NO 3 ) 3 $9H 2 O and NiCl 2 $6H 2 O were dissolved in distilled water. The oxides powders ZnO and Al 2 O 3 of purity (99.99%) were dissolved in nitric acid.…”

“…Beji et al 11 prepared a series of polyol-made Ni-Zn ferrite nanoparticles with varying annealing temperatures to optimize the structural and magnetic properties and found that heating at different temperatures ranged from 400 to 800 C provides changes of the magnetic properties of these particles. In our earlier work, 23 we investigated the dielectric properties of Ni 0.6 Zn 0.4 Fe 1.5 Al 0.5 O 4 annealed at 600, 900, and 1200 C. It was found that the dielectric properties of the system improved on increasing the temperature. Moreover, K. Praveena et al 24 discussed the effect of annealing temperature in dynamic magnetic properties of Ni 0.4 Zn 0.2 Mn 0.4 Fe 2 O 4 nanoparticles.…”

Synthesis, structural and electrical characterization of a new organic inorganic bromide: [(C3H7)4N]2CoBr4

“…[54][55][56] Also, the variation of 3 0 shows a peak at a critical transition temperature T c ¼ 403 K. As the temperature increases, the dipoles follow the variation of the eld which becomes too rapid so the real value of 3 0 decreases. 57,58 Furthermore, there is no displacement of the dielectric maximum with the increase in frequency, thus con-rming that the dielectric constant has a classical thermal evolution. 59,60…”
