Figure 3: (a) The energies of the considered magnetic configurations as a function of the lattice constant for . The solid line represents the energy curve of and the dashed lines represent the energy curves of the magnetic metastable configurations. (b) The energies as a function of the lattice constant for the distorted configurations (dashed lines) and the perfect configuration (solid line). The energy at the equilibrium volume of the configuration is taken as a reference.
