The x-ray structural properties of samples in the CuGaxAlxFe2−2xO4 (x = 0−0.7) and CuGaxAl2xFe2−3xO4 (x = 0−0.5) systems are studied. It is found that magnetic ordering in dilute copper ferrites affects their structural properties. It is concluded that the frustration of magnetic coupling leads to suppression of the cooperative Jahn-Teller effect in dilute copper ferrites with a frustrated magnetic structure.
