FTIR spectra and elastic properties of Cd-substituted Ni–Zn ferrites

Solid solutions Ni 0.5– x Cd x Zn 0.5 Fe 2 O 4 ( x = 0, 0.15, 0.30) were prepared by solid-state synthesis and characterized by FTIR spectroscopy. The FTIR spectra of synthesized ferrites showed two absorption bands (ν 1 and ν 2 ) in the range 400–600 cm –1 belonging to tetrahedral (A) and octahedra...

Description
Summary:Solid solutions Ni 0.5– x Cd x Zn 0.5 Fe 2 O 4 ( x = 0, 0.15, 0.30) were prepared by solid-state synthesis and characterized by FTIR spectroscopy. The FTIR spectra of synthesized ferrites showed two absorption bands (ν 1 and ν 2 ) in the range 400–600 cm –1 belonging to tetrahedral (A) and octahedral (B) interstitial sites in the spinel lattice. The force constants for tetrahedral ( K t ) and octahedral sites ( K o ) were determined, as well as Young’s modulus ( E ), rigidity modulus ( G ), bulk modulus ( B ), Debye temperature (Θ D ), and velocity of transverse ( V t ) and longitudinal ( V l ) elastic waves. The relevant interionic cation–anion, cation–cation distances and bond angles are also reported.
