Domain wall propagation and pinning induced by current pulses in cylindrical modulated nanowires

. Thermal modelling indicates that large current densities temporarily raise the temperature in the nanowire above the Curie temperature, leading to nucleation of domain walls during the system cooling. Micromagnetic modelling with a spin-torque effect shows that for intermediate current densities, Bloch …

Domain Wall Propagation and Pinning Induced by Current Pulses in Cylindrical Modulated Nanowires

Cristina Bran, Jose Ángel Fernández-Roldán, Julián A. Moreno, Arantxa Fraile Rodríguez et autres

The future developments of three-dimensional magnetic nanotechnology require the control of domain wall dynamics by means of current pulses. While this has been extensively studied in planar magnetic strips (planar nanowires), few reports exist in cylindrical geometry, where Bloch point domain walls …
