Abstract
Preisach analysis is applied to the study of hysteresis loops measured for different
angles between the applied magnetic field and the common axis of ferromagnetic Nickel
nanowire arrays. When extended to Ferromagnetic Resonance (FMR) lineshapes, with same
set of parameters extracted from the corresponding hysteresis loops, Preisach analysis
shows that a different distribution of interactions or coercivities ought to be used
in order to explain experimental results. Inspecting the behavior of hysteresis loops
and FMR linewidth versus field angle, we infer that angular dependence might be exploited
in angle sensing devices that could compete with Anisotropic (AMR) or Giant Magnetoresistive
(GMR) based devices.
