Density functional theory calculations within the generalized gradientapproximation are employed to study the ground state of Co2FeAl. Variousmagnetic configurations are considered to find out its most stable phase. Theferromagnetic ground state of the Co2FeAl is energetically observed with anoptimized lattice constant of 5.70 {\AA}. Thereafter, the system was subjectedunder uniform and non-uniform strains to see their effects on spin polarization(P) and half-metallicity. The effect of spin orbit coupling is considered inthe present study. Half-metallicity (and 100 % P) is only retained underuniform strains started from 0 to +4%, and dropped rapidly from 90% to 16% forthe negative strains started from -1% to -6%. We find that the present systemis much sensitive under tetragonal distortions as half-metallicity (and 100% P)is preserved only for the cubic case. The main reason for the loss ofhalf-metallicity is due to the shift of the bands with respect to the Fermilevel. We also discuss the influence of these results on spintronics devices.
