Abstract

The crystallographic properties of the oxidic spinel CuMn2O4 are investigated by neutron diffraction method. The present study indicates that CuMn2O4 is about 25% inverted. The value of the oxygen parameter 'u' is found to be 0.2629. Further it is possible to assign the structural formula (Cu2+0.50Cu1+0.25Mn3+0.25) [Cu2+0.25Mn3+1.50Mn4+0.25] O2-4 which satisfactorily explains the observed properties of the compound.
