Query: Antichiral Ferromagnetism   Here by combining a symmetry-based analysis with numerical computations we
predict a new kind of magnetic ordering - antichiral ferromagnetism. The
relationship between chiral and antichiral magnetic order is conceptually
similar to the relationship between ferromagnetic and antiferromagnetic order.
Without loss of generality, we focus our investigation on crystals with full
tetrahedral symmetry where chiral interaction terms - Lifshitz invariants - are
forbidden by symmetry. However, we demonstrate that leading chirality-related
term leads to nontrivial smooth magnetic textures in the form of helix-like
segments of alternating opposite chiralities. The unconventional order
manifests itself beyond the ground state by stabilizing excitations such as
domains and skyrmions in an antichiral form.
