<abstract xmlns="http://www.w3.org/1999/xhtml">Two series of Mn-Zn nanoferrites (namely Mn1-xZnxFe2O4 and Mn1-xZnxFe2-yRyO4) were synthesized using standard ceramic technique.

The X-ray density for each sample increased after laser irradiation which was correlated with the decrease in the unit cell volume. The study involved the thermal and frequency variation of the dielectric constant and AC conductivity of the investigated samples before and after laser irradiation. The later altered the conductivity by decreasing its value for the rare earth doped samples except for the Sm3+ doped one.
