Claims

C1strongest claim

Two dynamical modes play separate roles in the emergent impedance: translational motion of the domain-wall center generates a contribution proportional to its velocity, while time-dependent canting of the sublattice magnetizations localized within the moving domain wall produces a contribution whose magnitude is inversely proportional to the antiferromagnetic exchange coupling constant; their competition determines the sign and magnitude of the imaginary part at sub-resonant frequencies.

C2weakest assumption

The combined action of spin-transfer torque and spinmotive force, previously established for spiral magnets, remains the dominant mechanism for generating emergent impedance when applied to antiferromagnetic domain walls, with no additional damping or disorder terms required to alter the derived analytical expressions.

C3one line summary

Analytical expressions for emergent impedance in antiferromagnetic domain walls show separate contributions from translational motion proportional to velocity and from time-dependent sublattice canting inversely proportional to exchange coupling, with their competition setting the imaginary part at低
