Figure 4

(a) Stress-strain, (b) magnetic moment-strain and (c) energy-strain relationships for oP10[58]- CrB4, oP10[58]- MnB4 and oP10[58]- FeB4 along the weakest shearing path. The deformation paths are indicated in the figures. The snapshots of deformed bond structure and VCDD viewed along crystallographic [001] direction, i.e. z axis in Cartesian coordinate system at shear strain of (d) γ = 0.0000, (e) γ = 0.1717 (at peak) and (f) γ = 0.4002 (after instability) for CrB4 along the weakest (110)[1–10] slip system, and (g) γ = 0.0000, (h) γ = 0.2434 (at peak), and (i) γ = 0.4002 (after instability) for FeB4 along the weakest (110)[001] slip system. The black arrows in (d–i) indicate the position of bond instability.
