Query: Possibility of Emergence of Chiral Magnetic Soliton in Hexagonal Metal
  Formate [NH4][M(HCOO)3] with M2+ = Mn, Fe, Co, and Ni and KCo(HCOO)3   Search of chiral magnetic solitons on the basis of the data on the crystal
structure is important from both fundamental and technological points of view.
Potential chiral magnetic solitons - hexagonal metal formates [NH4][M(HCOO)3]
with M2+ = Mn, Fe, Co, and Ni and KCo(HCOO)3 containing dominating left-handed
chiral antiferromagnetic helices that compete with interhelix interactions have
been identified. The sign and strength of magnetic interactions not only
between nearest neighbors, but also for longer-range neighbors in the metal
formates have been calculated on the basis of structural data. Magnetic
structures of these compounds are similar to that of the chiral magnetic
soliton Cr1/3NbS2. The interrelation between chiral polarization of crystalline
and magnetic structures in the metastable polymorph KCo(HCOO)3 has been
demonstrated.
