Use of density functional theory to investigate the optical and magnetic behaviours of Ge1-xMnxTe half-metallic ferromagnets

Control of spin on ferromagnetism and thermoelectric properties of Sr(V/Cr)2S4; emergent spintronic aspirant

“…MM value for SrCr 2 S 4 decreases from 4μ B to 2.33μ B following similar p-d hybridization between the p-and 3d-states of S and Cr, respectively (see table 2). Because of the edge splitting of valence and conduction bands caused by this hybridization, two constants, N 0 α and N 0 β, called exchange splitting constants, are produced [46]. The positive/negative values of exchange constants N 0 α/N 0 β demonstrate the existence of antiparallel alignment for s-d coupling at V .B.…”

Study of ferromagnetism and thermoelectric behaviour of thiospinels MgFe2(S/Se)4 for spintronics and energy harvesting

“…In the case of MgFe 2 S 4 , MM is reduced from 4 μ B to 1.33 μ B, and for MgFe 2 Se 4 is reduced from 4 μ B to 1.69 μ B due to p-d hybridization among p-states of S/Se and Fe-3d states (see table 2). This hybridization causes VB and CB edge splitting which introduce exchange splitting constants like N 0 α and N 0 β [45]. In these exchange constants, N 0 α is positive while N 0 β is negative, which shows the antiparallel alignment of s-d coupling at VB, p-d coupling at CB.…”
