Structural and Microhardness Studies of Rare-Earth Doped Ruddlesden−Popper Manganites
We investigate the explicit role of the A-site doping by Pr and Sm on the mechanical and structural features of the lanthanum based double-layered manganites. The polycrystalline samples of the Ruddlesden-Popper (La1-yREy)1.4Ca1.6Mn2O7 phase with RE: Pr and Sm are elaborated by the solid-state synth...

| description | We investigate the explicit role of the A-site doping by Pr and Sm on the mechanical and structural features of the lanthanum based double-layered manganites. The polycrystalline samples of the Ruddlesden-Popper (La1-yREy)1.4Ca1.6Mn2O7 phase with RE: Pr and Sm are elaborated by the solid-state synthesis route. Powder X-ray analysis reveal that the samples structure is tetragonal (I4/mmm space group) and the lattice parameters do not change significantly with the rare-earth substitution. However, SEM analyses demonstrate that the substitution with Pr and Sm affects the microstructure, significantly. Whickers micro-hardness measurements are performed on both samples to evaluate several structural parameters such as the stiffness, creep, micro-hardness, etc. We compare and construct the mechanical and microstructural changes due to the Sm and Pr doping with La site. The detailed explanations for the observed mechanical changes by Pr and Sm doping is given. |
