Trajectories of magnetization projected onto the x-z plane for Stoner-Wohlfarth grains at 0 K. They are under the field condition of (a)Hdc = 31 kOe, Hac = 0.4 kOe and (b)Hdc = 30.0 kOe, Hac = 0.6 kOe. The field incident angle is 45°. (c, d) Present trajectories of magnetization projected onto the x-y plane in the early stage of magnetization switching processes corresponding to (a) and (b), respectively.
