Supercurrents in superconductor/altermagnet hybrids generate a tunable Néel torque that can propel domain walls and reverse Néel vector orientation.
Symmetry analysis predicts anisotropic thermomagnonic torques in insulating altermagnets that induce domain-wall precession and direction-selective skyrmion motion under temperature gradients.
