ELECTRON SPIN RESONANCE RESPONSE OF BaFe12O19 NANOPARTICLE EMBEDDED POLYDIVINYLBENZENE MAGNETIC FILM

Abstract

Electron spin resonance (ESR) spectra of the produced BaFe₁₂O₁₉ nanoparticles embedded poly divinylbenzene magnetic film were recorded depending on the ESR power. The ESR experiments were performed at seven different power values from 0.01 to 10 mW. ESR signal amplitude was observed to change exponentially with the applied ESR power. The ESR values of the film were found to be at a microwave frequency of 9225 MHz and a magnetic field of 296 mT. The effective gyromagnetic ratio, g_eff, of the film was calculated by using the room temperature ESR data. It is concluded that the produced magnetic film has a strong transitions of g_eff~2.23. The source of the ESR signals are Fe³⁺ S-state ions belonging to BaFe₁₂O₁₉ nanoparticles.
