Magnetization plateaus and frequency dispersion of hysteresis on frustrated dipolar array |
(a) Different hysteresis loops when different frequencies of magnetic field are applied with T = 0.1, H 0 = 10. For the quasi-static hysteresis under H 0 > 8 conditions, magnetic saturations, whose magnetic structures are the same as the third situation in Fig. 2(b) , are always attained. (b) The peak of the hysteresis dispersion moves upwards and shifts rightwards gradually with increasing field amplitude H 0. In addition, A ∝ 1/ f can be obtained when frequency is high. |
