Abstract
In this paper, based on the density functional theory (DFT) using full potential linearized augmented plane waves (FP-LAPW) method, some structural and mechanical properties of the Co2TiGe full-Heusler have been investigated. The structural optimization shows that calculated lattice constant is in a good agreement with reported experimental value and is better than reported theoretical investigations. The elastic coefficients have been calculated and based on the elastic constants the mechanical stability, and ductility of the compound have been studied. Our results show that this compound is mechanically stable and according to the Pugh’s ratio this compound is ductile material. This results is in agreement with the Frantsevich’s criterion because the value of Poisson's ratio for this substance is about 0.7, which is higher than the criterion of 0.33.
