Abstract

The aim of this work is to study the structural evolution and stability of ACoF₃ (A: K, Rb) undistorted perovskites under high-pressure conditions within the hydrostatic regime (below 10GPa). Attention is paid to their distortion propensity, extending the pressure range for this purpose. The role of A cations on the crystal compressibility, which can shed light on the mechanism governing the high-pressure evolution of oxides, has been explored. The results are compared with previous reports on the ABF3 family and point out the relevance of d-electron bonding in the crystal compressibility.
