Reply to “Comment on ‘Colossal dielectric and magnetodielectric effect in Er2O3nanoparticles embedded in a SiO2glass matrix”’

Abstract

In our earlier paper [Mukherjee et al., Phys. Rev. B 82, 104107 (2010)], we concentrated mainly on lower calcined transparent monolithic glass samples (particle size $l$10 nm) where interesting high-$k$ values with diffuse phase transition (DPT) and magnetodielectric (MD) behavior were observed. The Comment seems to focus on the sample calcined at 1200 ${}^{\ensuremath{\circ}}$C (particle size $g$40 nm), where the dielectric value is observed without DPT behavior. In this Reply we argue that, contrary to the conclusion of Hreniak et al., the disappearance of the MD effect is not only due to structural reorganization via crystallization of a different phase, but very much depends on particle size.
