TL;DR: In this article, the linewidth of a series of Permalloy films with thicknesses of 50 and 100nm was measured using linear function of frequency, with a slope that corresponds to a nominal Landau-Lifshitz phenomenological damping parameter α value of 0.007 and zero frequency intercepts in the 160-320A∕m (2-4Oe) range.

TL;DR: Heusler alloys are theoretically predicted to become half-metals at room temperature (RT) and by employing these ferromagnetic alloy films in a spintronic device, efficient spin injection into a non-magnetic material and large magnetoresistance are also discussed.
