| Özet |
| We report an orderly study on the structural and dielectric properties of Ni0.5Zn0.5Cr0.5Fe1.5O4 nanoparticles (NPs) synthesized by a polyethylene glycol (PEG)-assisted hydrothermal technique. XRD, FT-IR, FE-SEM and EDX measurements were implemented for the structural, morphological and compositional investigations of the product. Dielectric spectroscopy was used for the dielectric property investigation of the sample. Average particle size of the nanoparticles was estimated using Debye--Scherrer's equation as 34nm. Electrical properties of the sample have been investigated in the range of 1Hz to 3MHz (233--412K). It is observed that the sample has a giant dielectric constant approaching to 106 within the examined temperature range. It is also determined that the sample exhibits a dispersive phase transition around 305K at which this giant value of dielectric constant has been obtained. This transition ... |
