A solid solutionof (1-x)(Li2Mn4O8) x(Li1Fe5O8) for 0 < x < 1 has been inves
tigated by Mossbauer spectroscopy at room temperature and at 80 K. The satu
rated magnetic moment has been measured for x > 0.6. The results are explai
ned by a change of site preference of the Li ion from the tetragonal (A) si
te at x = 0 to the octahedral [B] site at x = 1.
