Abstract
We report on the domain wall magnetoresistance of Co and Ni nanowires of 45 nm on diameter or less. The enhancement of the resistance due to an isolat ed domain wall is clearly evidenced from magnetoresistance hysteresis loops obtained under parallel and perpendicular fields. The domain walls magneto resistance effect is by one order of magnitude smaller in Ni than in Co and it was observed only at low temperature for Ni nanowires, The formation an d motion of domain walls is demonstrated by MFM experiments.
