چکیده انگلیسی
Full-potential linearized augmented plane wave (FP-LAPW) method is applied to calculate the structural, electronic and magnetic properties of A2BBâ²O6 (A = Ba, Sr) and (BBâ²Â = FeRe, MnMo, and MnRe). The structural properties in cubic phase are studied at optimized volume. Electronic band structures are calculated by using the most efficient modified generalized gradient approximation for both spin-channels. This revealed that these materials have metallic behavior while some revealed half metallic behavior in generalized gradient approximation plus Hubbard parameter (GGA+U). Spin orbit (SO) coupling effects added to GGA+U reveal that all the compounds have semiconducting nature in both spin channels. Density of states shows that valence band has the majority O-2p state character while conduction band is dominated by the Fe/Re, Mn/Mo, and Mn/re-d state. The evaluated magnetic moment shows the utility of these compounds for the spintronics applications of these compounds.
