The aim of this paper is the prediction of the structural, electro-magnetic and mechanical properties of the Co(2)HfZ (Z = Al, Ga, Si and Sn) full Heusler compounds using a full-potential linearized augmented-plane wave method (FP-LAPW) based on the Wien2k program. For the structural and mechanical properties, we used the Perdew-Burke-Ernzerhof Generalized Gradient Approximation (PBE-GGA) and modified Becke and Johnson (mBJ) schemes to compute the fundamental parameters. The latter was employed for the electromagnetic properties, to calculate the band structures (BS) and density of states (DOS) of these compounds. Our results showed the half-metallicity of Co(2)HfZ (Z = Al, Ga, Si and Sn). The obtained energy revealed that these alloys were thermodynamically stable and could be hence elaborated experimentally. The mechanical properties indicated that our compounds were anisotropic ductile materials. Our findings greatly support that these compounds are highly attractive potential candidates for electro-spintronic applications. (C) 2021 Elsevier B.V. All rights reserved.
