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.
