Abstract

In oxides characterized by the $K_2NiF_4-type$ structure, the low-spin${\to}$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 $K_2NiF_4$-structure and the local structural distortion of the $(CoO_6)$ octahedron.
