Figure 6. Upper panels: Schematic view of the three magnetic configurations: the ferromagnetic EFM, antiferromagnetic EAF, and collinear antiferromagnetic Ecol spin arrangements.
Lower panels: Schematic plot of the exchange parameters J1 and J2, magnetic bond energies EF1 and EA1 between the nearest V-V moments, and EF2 and EA2 between the next-nearest V-V moments.
