Abstract
Data coding by current-driven domain wall (DW) depinning/pinning assisted by Oersted field was proposed and selective control of DW position was achieved in a perpendicularly magnetized wire in micromagnetic simulations. Sequential operations of logic operation following data coding have also been numerically demonstrated for spin wave and DW-based device. Inductive detection of interferrometric spin wave packets whose phase has been shifted by a DW pair showed successful logic operation in the optimized current pulse sequence applied for controlling the DW positions.
