Query: Anti-chiral order and spin reorientation transitions of triangle-based
  antiferromagnets   We show that triangle-based antiferromagnets with "anti-chiral" order display
a non-trivial dependence of the spin orientation with an in-plane field. The
spins evolve from rotating in the opposite sense to the field at very low
fields to rotating in the same sense as the field above some critical field
scale. In the latter regime the system displays first order transitions at
which the spin angles jump, and these first order lines terminate in critical
points in the Ising universality class. Application to Mn$_3$Sn is discussed.
