摘要：
Erbium (Er3+) dopednickel zinc ferrites with generic formula Ni0.5Zn0.5ErxFe2-xO4 (with x = 0, 0.025, 0.05) were synthesized by citric acid mediated sol-gel auto-combustion method. Structural and morphological characterization of the samples was respectively done by X-ray diffraction and transmission electron microscopic techniques. Fourier transform infrared spectroscopic studies of the samples were also done. Effect of Er3+ ion incorporation on the dielectric properties of the samples at room temperature over a wide frequency range (100 Hz-10 MHz) were studied by a LCR meter.Sample with erbium (x) = 0.025 percentage doping with relatively higher dielectric constant and lower dielectric loss value with respect to the pure nickel zinc ferrite showed a good possibility in high frequency applications.
