Microwave and magneto-optic properties of ε-Fe2O3 nanoparticles arising in borate glasses doped with Fe and Gd
Abstract
<jats:p>The ε-Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> nanoparticles in borate glasses co-doped with low concentrations of Fe<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> and Gd<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> were investigated with two experimental techniques – visible magnetic circular dichroism (MCD) and electron spin resonance (ESR). The most prominent features of the MCD spectra are: non-linear dependence of the spectral maxima intensities on the Gd concentration and strong increase with the temperature decrease. The ESR spectra of these glasses exhibit two features with g = 4.3 due to the diluted Fe<jats:sup>3+</jats:sup> ions and 2.0 associated both with Fe<jats:sup>3+</jats:sup> ions and with nanoparticles. The integrated spectra intensities do not follow the T<jats:sup>-1</jats:sup> Curie law suggesting a considerable contribution from the magnetically ordered nanoparticles to ESR. Analysis of the MCD and ESR concentration dependences allow suggestion on the Gd ions incorporation into nanoparticles.</jats:p>
