In order to explore an "anomalous" conduction phenomenon in the system Zn_(1-x)FeCrO₄Ni_x which was investigated with Mossbauer spectra, X-rays diffraction, Infrared spectra and other methods. The results show that the conductivity anomaly is not an intrinsic behavior but arises from the moisture-adsorption. Their native conduction is similar to that of semiconductors, obeying the relationship σ= σ_∞ exp (E_a/KT). All samples crystallize in cubic symmetry and their lattice parameters increase with x. The cation distribution is ( Zn_(1-x)Fe_x) [Fe_(1-x)Ni_xCr]O₄. No phase change occurs in the temperature range from 283 to 423 K.
