Study of Dielectric and Magnetic Properties for ZnFe2O4 Nanoparticles Synthesized Using High-current Exploding Technique

The current article uses the exploding wire technique to examine the magnetic, electrical, and dielectric properties of nanoscale zinc copper ferrite (ZnFe2O4). The SEM micrographs confirm the almost uniform size distribution of the nanoparticles. The Mossbauer spectrum of the nanoparticles was recorded with an externally applied magnetic field at room temperature. The ferromagnetic behavior of the ZFO sample was determined through VSM measurements at ambient temperature, and the M-H loop analysis yielded information on the magnitude of remanence, coercivity, and optimum magnetization. Our findings indicate that the ZFO sample is ideal for applications requiring switching magnetic properties between ferromagnetic and paramagnetic states. The dielectric properties, including the frequency-dependent dielectric parameters, were determined using an LCR meter, and the dielectric relaxation phenomenon was found to be governed by a technique similar to Arrhenius. Additionally, we plan to investigate the magnetodielectric response (MDR) of the ZnFe2O4 nanoparticles under different external magnetic field strengths at specified frequencies and temperatures. Overall, the facile and economical nano ferrite produced through a high-output synthesis technique is highly appealing for electronic devices requiring fine-tuning magnetodielectric features.
