Fig. 1: CuMnAs unit cell, Brillouin zone, and LEED.
From: Experimental electronic structure of the electrically switchable antiferromagnet CuMnAs

a Real space unit cell depicting the magnetic moments on the Mn atoms with arrows. b Tetragonal Brillouin zone, labeling high symmetry points. c, d LEED patterns from a decapped sample taken with 33 and 151 eV electrons, respectively. The blue diamond encloses an expected peak from tetragonal CuMnAs, while the red circles enclose extra peaks from 2×1 and 1×2 surface reconstruction domains. c The blue (red) dashed circle is drawn with a radius of \(\frac{2\pi }{a}\) (\(\frac{2\pi }{2a}\)) where a is the in-plane lattice constant of CuMnAs.
