SpinWave Dynamics in Antiferromagnets under Electric Current
20211228
Electric current causes a Doppler effect in spin waves in ferromagnets through a spintransfer torque. We report that antiferromagnets allow two such spintransfer torques and present a microscopic analysis that interpolates ferro and antiferromagnetic transport regimes.
