Abstract
AbstractAn investigation on the local magnetization processes within patterned permalloy films was performed by means of focussed magneto‐optic Kerr effect (MOKE) measurements, from which local magnetic hysteresis loops of the individual elements were found to be dependent on the separation between the individuals as well as the position in the array. When the separation between elements is larger than the element size, positions of elements in the array is relatively less influential on the behaviour of the magnetic hysteresis loops which are just the contribution of an individual element. When the separation between elements is close to the element size, the magnetic anisotropy shown in the magnetic Kerr loops is affected by the element position indicating that the magnetic interaction should be taken into account, which is also confirmed by the Micromagnetic simulations.
