We report an experimental investigation of the electronic structure and magnetic properties of bulk and nanosized MnCo2O4 diluted with Zn. The cationic distribution for tetrahedral A-site dilution is (Co2+1−yAZn2+yA)A[Mn3+Co3+]BO4±δ, whereas B-site dilution results in (Co2+)A[Mn3+1−xBZn2+xBCo3+]BO4−...
