This paper reports on the first study of the temperature and field dependences of the magnetization, heat capacity, and electrical
properties of synthesized polycrystalline samples of aerugite Co
10Ge
3O
16, as well as on x-ray diffraction analysis of this compound. It is shown that the cobalt ions in this compound occupy three
nonequivalent positions. The results of the experimental and theoretical studies suggest that aerugite is a ferrimagnet with
two uncompensated magnetic moments of the cobalt atom per formula unit.
