Abstract
The IR absorption spectra of tetragonal copper manganite CuxMn3−x O4 spinels (O 0.60 in conformity with that recorded by our previous measurements and have warranted the existence of a more complex cation distribution than that proposed earlier. It has been concluded from this study that the ionic configuration for x 0.60 to (Cux−y+Mn1−x+y2+)A(Cuy2+Mn2−x−y3+Mnx4+)BO42−, where y represents a low value (less than 0.20).
When the oxidation of Mn2+ and Cu+ ions is achieved below 450 °C, IR absorption measurements confirm the formation of a cation-deficient metastable spinel phase Cu1.5Mn1.5O4+δ with a 1:3 octahedral superstructure.
