Upon cooling below the N\\'eel temperature, $T_N = 420$~K, Larmor diffraction reveals the formation of magneto-structural domains of characteristic size $\\sim 240$~nm. In the antiferromagnetic state, dilatometry reveals a minute ($4 \\times 10^{-6}$) orthorhombic distortion of the crystal lattice in external magnetic fields. We","authors_text":"A. Erb, B.
