Figure 3: Dissipationless trajectories of motion of sublattice magnetizations and for an ideal antiferromagnetic particle. Nutations of the magnetization vectors with for (a) −1.003 and (b) −0.999. Nutations of the magnetization vectors with values m = (c) 0.08 and (d) 0.075 for . Panel (a) shows 23 initial nutations whereas panels (b)–(d) show the first nutations. Points show minimum and maximum values of projections and during nutations. |
