Depending on introduced barium concentration Nd1-xBaxCo1-yFeyO3-delta oxides have been crystallized in the orthorhombically distorted (x = 0.05, sp. gr. Pbnm), cubic (0.6 <= x <= 0.9, sp. gr.

Average values of thermal expansion coefficients for the Nd1-xBaxCo1-yFeyO3-delta oxides (0.8 <= x <= 0.9 and 0.7 <= y <= 0.9) visibly increased with temperature from (13.5-14.5) x 10(-6) K-1 at 300-700 K up to (23.2-26.2) x 10(-6) K-1 at 700-1373 K.",
