| Popis: | 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. 14 pages, 10 figures,3 tables, published version in J Supercond Nov Magn 2016 |
