Abstract
We have investigated the effects of 24.3 at% Dy substitution on the La site in the ferromagnetic perovskite 0.7Ca0.3MnO3. Results show a randomly canted ferromagnetic state below 65 K with a reduced metal–insulator transition. There is no breakdown of ferromagnetic domain structure at T < 65 K (covering the temperature range below 35 K where resistivity shows an upturn, indicating a reentrant transition to an insulating behaviour). Reduced geometrical tolerance factor and increased variance of the La-site ionic radius are responsible for the observed changes.
