Electro-mechanical character of Gd and Gd2In and possibility of a Kondo-like behavior in Gd2In

•The elastic constants of Gd and Gd2In using DFT with PBE/PBE+U were calculated.•We found out the relationship between Bulk and Shear moduli with c.e.c.•We found the possibility of Kondo-like behavior in Gd2In through the Poison’s ratio.•Through DOS, we found the possibility of c.e.c around the magnetic ions in Gd2In.•We found out the reduction of magnetic moment due to the induced spin polarization.

The elastic constants of Gd-element and Gd2In have been determined by density functional theory (DFT). Mechanical properties have been specified and compared with available experimental results. In this work, a detailed ab initio study on Gd and Gd2In are presented in order to investigate the magneto-elastic and electronic properties and to consider the tune parameters involved in these values. The relationship between these data and the possibility of Kondo-like effect in Gd2In were discussed.
