Phase and structural behaviour of new mixed
cobaltites R1-xR’xCoO3 (R, R’ = La, Pr, Nd, Sm, Eu, Gd) and cobaltites-chromites RCo0.5Cr0.5O3 (R = Pr, Sm, Eu, Gd) has
been studied in the temperature range of 298–1173K. Strong anomalies in the lattice expansion reflecting the changes in spin state of Co3+ ions, are found. Correlations between the structural parameters, characteristic temperatures of thermal expansion coefficients and the temperatures of spinstate transitions in the mixed RE cobaltites has been established.
