Local magnetization rotation in NiFe wire monitored by multiple transverseprobes

We have simultaneously measured the field dependence of transverse voltages at two pairs of transverse probes along with the magnetoresistance to dete ct the motion of ferromagnetic domain walls in a thin NiFe win. We observed sharp steplike changes of the transverse voltage correlated with the jumps in magnetoresistance, which have been reported previously in thin ferromag netic wires. The field dependence is explained in terms of the rotation of local magnetization near the transverse probes. This fact suggests that suc h a local magnetization rotation might contribute to some of the negative d omain-wall resistivity reported in recent papers.
