Nanowire arrays, surface anisotropy, magnetoelastic effects and spintronics.

Résumé

Resonance field Hres variation obtained from ferromagnetic resonance measurements performed versus field angle on ferromagnetic nickel nanowire arrays with different diameters (15 nm to 100 nm) and with temperature varying from liquid helium (4.2 K) to room value indicate presence of large surface anisotropy for small diameter (<50 nm) and strong magnetoelastic effects for all diameters. Extracting this information from temperature variation of anisotropy terms allows us to infer that magnetoelastic behavior versus temperature and nanowire diameter might have important implications for the design of nanowire based spintronic devices such as magnetic racetrack memory, logic and storage media, and devices.
