Structural, Elastic and Mechanical Properties of Cubic Perovskite Materials

Abstract

In this manuscript, theoretical work has been done on series of cubic perovskites RbVF3, RbMnF3, RbFeF3, RbCoF3, RbNiF3, RbCuF3, and RbZnF3. The main focus is on to compute structural, elastic and mechanical properties of cubic materials. All subjected computational results are collected by using Linearized Augmented Plane Wave (FP-LAPW) method using Density Function Theory (DFT). The calculated structural parameters including initial geometry optimization, energy minimization calculations, and total energy values reasonably agree with the previous work. The elastic properties contain C11 (for length), C12 (for volume) and C44 (for shape). These constants are used for calculations of different parameters to discuss mechanical properties. The results show that series of RbMF3 (V, Mn, Fe, Co, Ni, Cu and Zn) contains metallic bonding and anisotropic behavior. The temperature increases from RbVF3 to RbZnF3.These materials are ductile by nature. However, among all materials, RbZnF3 is the hardest material and also contains highest melting temperature. Hence by calculating these useful elasto-mechanical results they can be applicable in various devices for technological benefits so the current investigation signifies that these calculations provide a baseline for new researchers to establish further work.
