We perform ab initio calculations of the electronic structure and conductance of atomic-size Ni nanowires with domain walls only a few atomic lattice constants wide. We show that the hybridization between noncollinear spin states leads to a reduction of the magnetic moments in the domain wall resulting in the enhancement of the domain wall resistance. Experimental studies of the magnetic moment...

The operating performance of a domain wall-based magnetic device relies on the controlled motion of the domain walls within the ferromagnetic nanowires. Here, we report on the dynamics of coupled Néel domain wall in perpendicular magnetic anisotropy (PMA) nanowires via micromagnetic simulations. The coupled Néel domain wall is obtained in a sandwich structure, where two PMA nanowires that are s...

Spintronic artificial spiking neurons are promising due to their ability closely mimic the leaky integrate-and-fire (LIF) dynamics of biological LIF neuron. However, neuron needs be reset after firing. Few spintronic that have been proposed in literature discuss process detail. In this article, we various schemes achieve a magnetic domain wall (DW)-based which position DW represents membrane po...
