abstract

MnTe has recently attracted attention as an altermagnetic candidate. Experimentally it has an altermagnetic order of ferromagnetic $ab$ planes, stacked antiferromagnetically along $c$. We show that this magnetic order (by itself non-trivial, since the in-plane exchange in antiferromagnetic) opens intriguing possibility of manufacturing altermagnetically-detwinned samples and generate observable magnetooptical response (which we calculate from first principles) as a signature of altermagnetism.

Discussion (0). Continue with ORCID to comment.

  1. Symmetry-Breaking Magneto-Optical Effects in Altermagnets

    cond-mat.mtrl-sci 2025-05 conditional novelty 6.0 of 10

    Uniaxial strain selectively breaks the symmetries that hide altermagnetism, producing detectable optical absorption and Kerr rotation that ordinary antiferromagnets do not show.

  2. Symmetry, microscopy and spectroscopy signatures of altermagnetism

    cond-mat.mtrl-sci 2025-06 unverdicted

    A review of the symmetry, microscopic origin, and detection of altermagnetism, a collinear magnetic phase with alternating spin polarization in momentum space.
