“…This deliberate engineering profoundly influences the crystal structure and the resulting magnetization value of the material. Recent research in doping Lanthanum-based perovskites [5][6][7][8] strengthens the argument that explained doping on the La site of lanthanum manganate material induces the presence of two valence states for Mn ions, namely Mn 3+ and Mn 4+ , due to double exchange interaction events. Furthermore, doping on the Mn site influences the double exchange interaction, altering the material's structural properties.…”

We conducted first-principles Density Functional Theory (DFT) calculations using the CASTEP software package to investigate the crystal structure and mechanical properties of Fe3+-doped La0.7Ba0.3MnO3 material at the Mn3+ site, with doping concentrations ranging up to 50%. Through geometry optimization, we simulated the X-ray diffraction (XRD) pattern. We observed that the doping of Fe did not result in a shift in the peak positions of the diffraction pattern. However, it led to an increase in intensity at the [012] peak and the splitting of peaks [104] and [110]. Regarding the mechanical properties, we examined the elastic constants and observed a reduction in the Bulk, Shear, and Young's modulus values. The Shear and Bulk modulus and Poisson's ratio indicated that La0.7Ba0.3Mn(1-x)FexO3 becomes less ductile with increased Fe3+ doping content. Furthermore, we performed calculations for the Debye temperature, which revealed a decrease in the thermal conductivity of the La0.7Ba0.3Mn(1-x)FexO3 material.
