Abstract
The profiles of MAE and BN for Co, Ni, oriented Fe–3.5% Si, and permalloy between − H max to + H max were investigated under 0.5 and 1 Hz triangle applied magnetic field. The profiles of Co (contained 180° domain walls only) under different H max and different frequency show that the peak to peak voltage of MAE increase when the H max and frequency are increasing, and the shape of the profiles of MAE is similar to that of BN under the same condition. But for Ni the shapes of profiles of MAE and BN are not similar to each other. It means that the sources of MAE and BN for Co are the same i.e. 180° domain wall motion. Not only the motion of non-180° domain wall but also 180° domain wall motion are the source of MAE. Besides that, domain wall nucleation and annihilation are also the sources of MAE.
