Fine phase control of domain walls in curved nanostripes: from bits to nits
Gabriel R. de Andrade Silva, Vagson Luiz de Carvalho Santos, Guilherme Henrique Rezende Bittencourt
We propose a physical mechanism for fine-tuning the phase of a domain wall around the equilibrium directions involving the application of an external field and a spin polarized cur…
