Solid solutions with a perovskite structure of the general formula A′1?xA″xMnO3 (including the previously unknown compounds with A′=La or Pr and A″=Cd or Bi) are studied. It is found that the structure of the orthorhombic phases formed from rhombohedral phases with a decrease in the temperature is characterized by strong anisotropy of the Mn-O bond lengths. This anisotropy drastically decreases at lower temperatures. |
