Figure 2: The curves of the total energy dependence to the anti-site disorder degree for the CoMnTiSi alloy with Co-Mn, Co-Ti and Mn-Ti anti-site disorder.
From: Anti-site-induced diverse diluted magnetism in LiMgPdSb-type CoMnTiSi alloy

The x represents to exchange x% of the atom number at a sublattice site and those at another sublattice site. The total energy of the ordered CoMnTiSi alloy was set as the zero point of Y axis.
