Abstract
Micro-size and nano-size samples of (GdxY3−xFe5O12; x = 0, 0.25, 0.5, 0.75, and 1) garnet ferrites were prepared by the standard ceramic method (CER) and the coprecipitation (COP) method. The influences of Gd3+ doping and preparation methods on the optical and dielectric properties were compared for these micro-size and nano-size compositions for the first time. X-ray diffraction data confirmed the formation of a single phase of the garnet cubic structure for all samples. It was found that there is a good agreement between the theoretical and experimental lattice parameter estimated values. The Fourier transform infrared spectroscopy was used to study the cation distributions among the different crystallographic sites. Moreover, values of energy gap (Eg) for the investigated samples were determined from the diffused reflectance spectroscopy measurements. These values were found to be higher for (COP) samples than for (CER) ones and slightly increased by increasing Gd3+ content in both series prepared via the two techniques. Furthermore, resistivity (ρac), dielectric constant (ε′), and dielectric loss (ε″) showed a decrease with increasing frequency (f) for all samples. For the samples prepared by (CER) method, ρac increases with increasing Gd3+ content while for the samples prepared by (COP) method, ρac increases for 0 ≤ x ≤ 1 except for the sample x = 0.5. Values of ρac for samples prepared by (COP) method are higher than those prepared by (CER) method. Both ε′ and ε″ had the reverse behavior of ρac. Obtained results were explained according to different models.
