The influence of non-magnetic central node defect on magnetic hysteresis of regular square-shaped segment of magnetic dot array with perpendicular uniaxial anisotropy under the thermal activation was investigated via computer simulations based on stochastic Landau-Lifshitz-Gilbert equation. The aim of this study is to point out the simultaneous effect of anisotropy and thermal activation to the dynamical properties of magnetic dot arrays. |
