  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.
