Magnetization plateaus and frequency dispersion of hysteresis on frustrated dipolar array

(a) A leap of the hysteresis area can be observed in low frequencies. (b) The shapes of hysteresis loops change with different amplitudes of magnetic fields applied at low frequencies ( f = 10−4 here). Only one steady state exists when H 0 = 6, but, for larger amplitudes, two steady magnetic structures exist.
