A magnetic spin-valve device composed of two nanowires connected by a nanosized constriction was prepared, on which the presence of a pinned DW by nanoconstriction was detected by giant magnetoresistance effect. When the magnetic wire has a nanoconstriction, the DW configuration and width were largely affected by the shape of nanoconstriction. An asymmetric magnetotransport behavior observed in the experiments was interpreted by a micromagnetic modeling study.Nanoconstrictionnanowiremagnetic domain wall (DW)magnetoresistanceMotiontext::conference output::conference proceedings::conference paper
