ABSTRACT
Optimal current pattern for domain wall (DW) dynamics in nanowires is investigated. Based on the modified Landau–Lifshitz–Gilbert equation with both the Slonczewski spin-transfer torque and the fieldlike torque, the optimal current pattern for either the maximal DW propagation velocity or the maximal DW-motion-induced spin electromotive voltage is found. Possible experimental realizations are discussed.

    We demonstrate the possibility to write and modulate the magnetic domain walls in a TbFeCo single layer nanowire (300 nm width, 150 μm length). To realize this, a tiny magnetic domain was nucleated by an Oersted field produced by a 1.6 MHz pulse current (35 mA in amplitude, 5-40 ns in length)...
