Ferromagnetic resonance and magnetoresistive measurements evidencing magnetic vortex crystal in nickel thin film with patterned antidot array
I. R. B. Ribeiro, J. F. Felix, L. C. Figueiredo +6
Ferromagnetic vortices deliver robust out-of-plane magnetization at extremely small scales. Their handling and creation therefore has high potential to become a necessary ingredien…
