Our study focuses on the dimensionality effect, so one or two dimensional assemblies have been considered. Opposite effects on the peak height and location of the two ac-susceptibility components have been observed, depending on the easy axis is in the plane of the assembly or perpendicular to it. Furthermore, we have investigated the energy barrier distribution in the presence of dipolar interactions. © 2014 The Authors. Published by Elsevier B.V.
