| Description |
Mg-Gd-Mn nanoferrites with formulae Mg0.9Mn0.1GdyFe2-yO4, where y=0.05, 0.1, 0.2 and 0.3, have been synthesized by solution combustion technique. The dc resistivity was observed to decrease with the increase in temperature. Dielectric constant (epsilon') and loss tangent (tan delta) have been found to be increasing with an increase in temperature while with an increase in frequency both have been found to be decreasing. The ac electrical conductivity (sigma(ac)) has been studied as a function of temperature at different frequencies and has been observed to be increasing with the increase in temperature. The Mossbauer spectroscopy has been carried out so as to authenticate our previously reported results on the super-exchange interactions.
