In this communication we report structural and dielectric properties of mixed Cu-Zn spinel ferrite nanoparticles. Cu (0.7) Zn (0.3) Fe 2 O 4 nanoparticles were synthesized by using standard and well known sol-gel auto-combustion techniques. The obtained nanoparticles were annulated at 520°C for 4 h and then used for further study. The X-ray diffraction (XRD) pattern was recorded at room temperature to investigate the single phase nanocrystalline nature of prepared sample. The XRD pattern shows formation of single phase cubic spinel structure with average crystallite size of ∼24 nm. The crystallite size was determined by using standard Scherrer’s equation. The other structural parameters like lattice constant, unit cell volume, X-ray density etc. were determined using XRD data. The dielectric properties were measured at room temperature and as a function of frequency using LCR-Q meter. The dielectric constant, dielectric loss and dielectric loss tangent all get decreased exponentially with increasing frequencies. The observed dielectric behaviour is similar to that of reported in the literature.
