| dc.description.abstract | In this work, we have carried out the study of a half-Heusler compound MnFeTe in
order to determine its structural,elastic, magnetic and electronic properties using the FP-
LAPW (Full Potential Augmented Linearized Plane Wave) method, based on the density
functional theory (DFT) as implemented in the WIEN2k code.The exchange-correlation
potential is treated by theWu-Cohen- generalized gradient approximation (GGA-WC). The
structural properties reveal that the obtained lattice constant is in good agreement with other
calculations. On the other hand, the obtained values of the elastic constants Cij with the
different elastic parameters such as the shear modulus (G), the Young's modulus (E) and the
Poisson's ratio (σ) as well as the bulk modulus (B) and its derivative are comparable to the
theoretical data where the mechanical stability of the material is verified.Calculation of
electronic properties reveals that the compound is a half metal with a magnetic moment of
3µB which is in agreement with the available value. | en_US |
