We present first-standards estimations on Fe, Nd, and SmCo5 utilizing the self-predictable maximum capacity linearized increased plane wave (FPLAPW) strategy. The attractive snapshots of Fe, Nd, and Smco5 were determined utilizing the WIEN2K code. The minutes for BCC Fe and HCP Nd are 2.27μB and 2.65μB separately in great concurrence with test esteems. For Smco5, we efficiently study the impact of considering the twist circle coupling and Coulomb connections in the Sm f shell on the attractive properties, electronic construction, and twist thickness maps. The determined attractive second and magneto-crystalline anisotropy like anisotropy are in acceptable concurrence with test esteems. The twist thickness maps in the (001) plane show that the impact of the twist circle coupling on the twist thickness design of Sm particles is more grounded than that of Coulomb connection. We additionally study the impact of the polarization heading on the energy groups by looking at the highlights of band structure when the charge bearing is along or opposite to the c-axis. The determined outcomes are in acceptable concurrence with the exploratory information.

Keywords: Density functional theory, Linearized augmented plane waves, Spindensity maps, Spin-orbit coupling.
