Abstract: We systematically probed the dynamics of two-dimensional Ni 80Fe20 nanowire arrays with different strengths of interwire interactions using angular dependent microwave absorption spectroscopy. The experimental results are analyzed in terms of a graphical representation of the resonant absorption data through a critical-curve-like approach. This representation has the advantage of offering a direct and complete visual representation of anisotropy, interactions, and magnetization dynamics effects in nanomagnet arrays. In the paper, the connection between the proposed image of polar resonant absorption curves and the static switching field critical curves is substantiated using both macrospin and fully micromagnetic simulation approaches. © 2013 AIP Publishing LLC.
