Abstract
In oxides characterized by the K2NiF4-type structure, the low-spin→high-spin transition of trivalent cobalt ion was studied in function of the nature of competing bonds in the perovskite-plane and along the c-axis. Using Slichter and Drickamer's model the calculated values of parameters characterizing such a transition are correlated with the covalency of competing bonds along the c-axis of the K2NiF4-structure and the local structural distortion of the (CoO6) octahedron.
