  We theoretically demonstrate dc and ac electric voltage generation due to
spinmotive forces originating from domain wall motion and magnetic resonance,
respectively, in two-sublattice antiferromagnets. Our theory accounts for the
canting between the sublattice magnetizations, the nonadiabatic electron spin
dynamics, and the Rashba spin-orbit coupling, with the inter-sublattice
electron dynamics treated as a perturbation. This work suggests a new way to
observe and explore the dynamics of antiferromagnetic textures by electrical
means, an important aspect in the emerging field of antiferromagnetic
spintronics, where both manipulation and detection of antiferromagnets are
needed.
