Abstract

Abstract: Ferromagnetic resonance spectroscopy is a powerful technique to analyse the dynamic properties of nanostructured materials. In order to understand the dynamic phenomena in these samples, nickel and permalloy nanostructured dot and line arrays have been prepared using interference lithography. Temperature dependence of the ferromagnetic resonance measurements have been carried out at a frequency of 9.5 GHz as a function of magnetic field from 85 K to room temperature. Nickel and permalloy based samples present a different temperature dependence of the resonance field, with decreasing and increasing values respectively with higher temperatures. Resonance linewidth in permalloy is nearly constant while nickel arrays present a small decrease with increasing temperature. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
