  text: Altermagnetism has recently emerged as a distinct class of collinear antiferromagnets
    that break time-reversal symmetry, exhibiting a host of novel properties. Applied
    strain has attracted particular attention as a key tuning parameter for altermagnets.
    Although several experimental studies have demonstrated the preparation of single-domain
    states through a combination of applied strain and magnetic field, the route to
    such states remains unclear. Here, we use magneto-optical measurements on single
    crystals of MnTe under applied strain to show that, in contrast to previous reports,
    strain acts primarily to rotate the Néel vector L continuously. Since the orientation
    of L determines the magnetic point group symmetry, this continuous rotation effectively
    tunes the symmetry and its associated physical properties. Furthermore, we demonstrate
    that built-in strain in free-standing crystals is sufficient to pin L into continuous
    textures over millimeter length scales. Together, these results provide guidance
    for future device design and open the door to leveraging the Néel vector orientation
    as a tunable degree of freedom in spintronic applications.
