Abstract
Structural magnetic and electrical measurements were carried out for the system NixCu1-xMn2O4 (0<or=x<or=1). Correlation of physical properties has been attempted in order to arrive at the ionic configuration for each composition of the system on the basis of existing theories. The cation valence distribution for NiMn2O4 has been obtained as Mn3+(Ni2+Mn0.12+Mn0.902+) O3.952-.
