Large magnetic moments were observed in the cubic spinel oxides Ge_xZn_<1-x> Fe_2O_4 (0<x<1). Lattice constant of this system deviates from the Vegard's law. Intensity analysis of X-ray powder diffraction indicates that approximately 30% of A site are occupied by magnetic ions in the case x=0.5. Ion distribution of the whole system is proposed which can explain the x dependence of the magnetic moment and the lattice constant. The distribution is shown to be reasonable from a view point of electric charge neutrality in a cluster of several cations and anions.
