含Mn，Fe，Co，Ni和KCo（HCOO）3的Hisponal金属甲酸盐[M2][M（HCOO）3]中出现手征磁孤子的可能性
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
摘要：
根据晶体结构数据研究手征磁孤子，无论从理论上还是从技术上都具有重要意义。潜在的手征磁孤子-六方金属甲酸盐[NH 4][M（HCOO）3]，其中M2+ = Mn，Fe，Co，Ni和KCo（HCOO）3含有与螺旋间相互作用竞争的主要左手手征反铁磁螺旋。在结构数据的基础上，计算了金属甲酸盐中最近邻和长程邻之间的磁相互作用的符号和强度。这些化合物的磁结构与手性磁孤子Cr 1/3 NbS 2的磁结构相似。亚稳态多晶型物KCo（HCOO）3的晶体手性极化与磁结构之间的相互关系已得到证实。
英文摘要：
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.
