Ferrimagnetism of manganese ferrite-chromite

A study of manganese ferrite-chromite by means of magnetic moment, electronic resonance, and neutron diffraction measurements shows clearly that a compensation composition exists when about half the iron is replaced by chromium, and that spiral spin configurations form when just over three-fourths the iron has been replaced. In the regions where these transitions take place, microwave resonance absorption curves become very broad and the effective g factor shifts to very large values. For the higher chromium compositions, there are discrepancies between the magnetic moment measurements and sublattice values from neutron diffraction, probably connected with the occurrence of spirals. © 1963.
