Calcium-doped lanthanum manganite La 1-x Ca x MnO 3 , synthesized by the glycine/nitrate method, was characterized by high resolution synchrotron X-ray powder diffraction, electron diffraction, and infrared spectroscopy. A strong correlation was observed between the cooling rate from the calcination
Strontium-doped lanthanum manganite Lal-xSrxMnOa (LSM) is characterized by hexagonal-rhombohedral distorted perovskite-type structure, deriving from the ideal cubic symmetry through rotation of the [MnO6] octahedra around the ternary axis. The extent of distortion and unit cell volume depend on Sr c
