Mn-Zn nano ferrites were synthesized with citric acid as a capping agent by sol gel auto combustion method.Synchrotron and laboratory x-ray diffraction confirms that mixed nano ferrites is crystalline in nature and indexed incubic crystal structure (space group Fd3m). Reduced crystallite size is obtained from Synchrotron (15.4 ± 0.0001 nm) ascompared to laboratory (16 ± 0.001 nm) source. Raman spectroscopy reveals a doublet like nature of A1g mode for MnZn nano ferrites. Dielectric constant (ε’) and loss (tan δ) measured in the frequency range from 100 Hz to 10 MHz atdifferent temperature are found to be decreasing along increase in frequency. The ac electrical conductivity of about0.108 Sm-1at 573 K is observed for Mn-Zn nano ferrites. Frequency dependent dielectric response supports the dielectricpolarization and electrical conduction mechanism. Minimum dielectric loss (~ 0.08) [300 K] at 10 MHz showed thatsynthesized Mn-Zn nano ferrites are desirable for high frequency applications
