Electromotive force induced by domain wall propagation in cylindrical magnetic microwire

Cylindrical nanowires are attracting an increasing interest, where Bloch-point DWs have been recently observed and calculated through micromagnetic simulations. The DW motion under controlled local magnetic fields and the effect of electrical current has been recently reported in microwires. In this study, we have experimentally measured the emf induced at the ends of a microwire and has been correlated with the controlled motion of single DWs that propagate along the microwire with strong uniaxial anisotropy.
