Abstract
Nanocrystalline powders of new mixed manganites-chromites RMn0.5Cr0.5O3 (R = Pr, Sm, Er) and manganites-gallates RMn1-xGaxO3 (R = Pr, Sm, Eu; x = 0.25, 0.5) with orthorhombic perovskite structure were obtained by sol-gel citrate route. Crytal structure parameters and microstructural parameters of the materials were established depending on the synthesis conditions. Based on the resuts obtained formation of conntinuos solid solutions RMn1-xCrxO3 in the RMnO3-RCrO3 systems and limited solid solitions in the RMnO3-RGaO3 systems were predicted.
