Dipolar interactions in arrays of ferromagnetic nanowires: A micromagnetic study

Year: 2011

Type: article

Abstract: We explore the behavior of periodic arrays of magnetic nanowires by micromagnetic simulations using the NMAG modeling package. A large number of modeling studies on such arrays of nanowires have been performed using finite size models. We show that these finite size micromagnetic descriptions can only be used in specific situations. We perform a systematic study of more or less dense one- and two-dimensional arrays of nanowires using either finite size or infinite size models and we show that finite size models fail to capture some of the features of real infinite systems. We show that the mean field model scaled to the system porosity is valid. This work can be used as a basis to the extension of micromagnetic calculations of the magnetization dynamics in arrays of nanowires.
