Enhancement of domain-wall mobility at the angular momentum compensation temperature detected by NMR

The angular momentum compensation temperature $T_{\rm A}$ of ferrimagnets is attracting attention because of high-speed magnetic dynamics near $T_{\rm A}$. Expand abstract.

Topological damping Rashba spin orbit torque in ballistic magnetic domain walls

Our identification of a topological damping Rashba spin orbit torque component in magnetic domain walls will help to understand experiments on current driven domain wall motion in ferromagnet/heavy metal systems with broken inversion symmetry and to facilitate its utilization in innovative device designs.

Domain wall melting in spin-1 chains

We conclude that on intermediate-large time scales the dynamics is well described by the integrable Landau-Lifschitz classical differential equation. Expand abstract.

Stabilization of coupled Dzyaloshinskii domain walls in fully compensated synthetic anti-ferromagnets

The existence of anti-ferromagnetically coupled Dzyaloshinskii domain walls (DWs) in a high DMI SAF is confirmed through application of in-situ perpendicular magnetic field and sample tilt. Expand abstract.

Walker breakdown with a twist: Dynamics of multilayer domain walls and skyrmions driven by spin-orbit torque

Above a critical current threshold, corresponding to typical velocities of the order tens of m/s, domain walls in some layers start to precess with frequencies in the gigahertz regime, which leads to oscillatory motion and a significant drop in mobility. Expand abstract.

The Atiyah-Patodi-Singer index and domain-wall fermion Dirac operators

Our viewpoint sheds some new light on the interplay among the Atiyah-Patodi-Singer boundary condition, domain-wall fermions, and edge modes. Expand abstract.

Domain wall and anisotropic magnetoresistance of the antiferromagnet Mn2Au

These results demonstrate a domain wall related origin of the large resistance effects and relaxation phenomena observed in current induced switching experiments of metallic antiferromagnets. Expand abstract.

Field-free spin-orbit torque switching through domain wall motion

Kerr imaging study further unveils that the observed switching is mainly dominated by domain nucleation and domain wall motion, which might limit the potentiality of using this type of multilayer stack design for nanoscale SOT-MRAM application. Expand abstract.
