متن کاملChiral damping of magnetic domain walls.
Structural symmetry breaking in magnetic materials is responsible for the existence of multiferroics, current-induced spin-orbit torques and some topological magnetic structures. In this Letter we report that the structural inversion asymmetry (SIA) gives rise to a chiral damping mechanism, which is evidenced by measuring the field-driven domain-wall (DW) motion in perpendicularly magnetized as...
متن کاملTunable inertia of chiral magnetic domain walls
The time it takes to accelerate an object from zero to a given velocity depends on the applied force and the environment. If the force ceases, it takes exactly the same time to completely decelerate. A magnetic domain wall is a topological object that has been observed to follow this behaviour. Here we show that acceleration and deceleration times of chiral Neel walls driven by current are diff...
متن کاملTunable resistivity of individual magnetic domain walls.
Despite the relevance of current-induced magnetic domain wall (DW) motion for new spintronics applications, the exact details of the current-domain wall interaction are not yet understood. A property intimately related to this interaction is the intrinsic DW resistivity. Here, we investigate experimentally how the resistivity inside a DW depends on the wall width Δ, which is tuned using focused...
متن کاملTunable Quantum Tunneling of Magnetic Domain Walls
Perhaps the most anticipated, yet experimentally elusive, macroscopic quantum phenomenon 1 has been spin tunneling in a ferromagnet 2 , which may be formulated in terms of domain wall tunneling 3,4. One approach is to focus on mesoscopic systems where the number of domain walls is finite and the motion of a single wall has measurable consequences. Research of this type includes magnetotransport...
