The Mossbauer spectra of the Ni_(1-x)Cd_xFeAlO₄ system were investigated with the Cd content x at room temperature. The spectra of the samples exhibit various patterns as follows 1) superparmagnetic relaxation for 0≤x≤0.2, 2) ferrimagnetic sextet for 0.3≤x≤0.5, 3) ferromagnetic relaxation for x=0.6, 0.7, 4) paramagnetic doublet for 0.8≤x≤1, with the Cd content x. In the samples with x values from 0 to 0.2, the substituted Cd²+ ions transfer the Al³+ ions from A-site to B-site mainly. The superparamagnetic relaxation effect and the ferromagnetic relaxation effect are derived from the Al³+, Cd²+ respectively. The magnetic structure of the Ni_(1-x)Cd_xFeAlO₄ system was explained by the Yafet-Kittel model.
