On the Relationship between Structural-Elastic Properties of Co-Zn Ferrites at 300 K

Abstract:

The structural - elastic properties correlations have been studied for polycrystalline spinel ferrite system, Zn_xCo_1-xFe₂O_4, x = 0.0-0.6, at 300 K. The cation distribution formulae determined from X-ray diffraction line intensity calculations are used to calculate bulk modulus (K_o) in particular and Young′s modulus (E₀), rigidity modulus (G₀), longitudinal modulus (L₀) and Lame′s constant (λ_L0) in general. The longitudinal wave velocity (V_l0) and transverse wave velocity (V_so) computed from empirical relation based on X-ray density and mean atomic weight is used to calculate L₀ and G₀ respectively. The applicability of the heterogeneous metal mixture rule for theoretical estimation of elastic constants has been tested. The results are compared with elastic moduli determined from conventional ultrasonic pulse transmission technique and causes for the observed difference between the two have been discussed.
