Abstract
Solid solutions Ni0.5–xCdxZn0.5Fe2O4 (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 (ν1 and ν2) 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 (Kt) and octahedral sites (Ko) were determined, as well as Young’s modulus (E), rigidity modulus (G), bulk modulus (B), Debye temperature (ΘD), and velocity of transverse (Vt) and longitudinal (Vl) elastic waves. The relevant interionic cation–anion, cation–cation distances and bond angles are also reported.
