    • Abstract

       

      Magnetic susceptibility studies of Mn1-xMxO (M = Zn, x≤0.1; M = Mg, x≤0.12;M = Fe, x≤0.4) in the range 77 to 300 K are reported. The methods of preparation of Mn1-xMxO systems preclude the presence of trivalent ions. The M1-xFexO system shows anomalous behaviour aroundx = 0.2–0.3. The results are discussed in terms of competition between the nearest neighbour and the next-near-neighbour interactions, dilution effects and cooperative effects of FeO6 octahedra.
