Popis:	A tetragonal (space group I4/mmm) solid solution La2-2x(Ca1-ySry)1 + 2xMn2O7 based on the Raddlesden-Popper phase (n = 2), which is formed by the simultaneous substitution of calcium in Ca3Mn2O7 by strontium and lanthanum, is synthesized by high-temperature annealing of La2O3, Mn2O3, CaCO3, and SrCO3 mixtures (1500°C, air). The concentration area of the solid solution in the scheme is a pentagon, whose corners correspond to the manganites Ca3Mn2O7, Ca0.75Sr2.25Mn2O7, La0.2Sr2.8Mn2O7, La1.6Sr1.4Mn2O7, and LaCa2Mn2O7.
