Abstract

La 0.7 Sr 0.2 Ba 0.1 Mn 1-x Ni x O 3 (x=0 and x=0.1) material has been successfully synthesized using sol-gel method. The XRD pattern shows the sample has a single phase without impurities. The result of refinement showed that both samples formed a rhombohedral structure with R-3c (167) space group. The addition of nickel ions with a concentration of 10% does not change the crystal structure, but causes a decrease in lattice parameters, unit cell volume, Mn-O-Mn Bond angle, and increase Mn-O Bond length. The unit cell volume of La 0.7 Sr 0.2 Ba 0.1 MnO 3 and La 0.7 Sr 0.2 Ba 0.1 Mn 0.9 Ni 0.1 O 3 are 353.382 Å 3 and 352.036 Å 3 . The MnO-Mn angle for both is 168.021° and 163.829°, while the Mn-O bond lengths are 1.9559 Å and 1.9624 Å respectively. Goldschmidt's tolerance factor was calculated to know the stability of the crystal structure. Tolerance factor calculation results confirm that the stable crystal structure is rhombohedral perovskite structure (0.97372 and 0.97154).
