We theoretically demonstrate dc and ac electric voltage generation due to spin motive 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 intersublattice electron dynamics treated as a perturbation. this work suggests a way to observe and explore the dynamics of antiferr...We theoretically demonstrate dc and ac electric voltage generation due to spin motive 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 intersublattice electron dynamics treated as a perturbation. this work suggests a 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.» weiterlesen» einklappen
