Abstract—
The study is devoted to the theoretical analysis of noncollinear magnetic structures of charge-ordered manganites with a doping level of x = 3/4, 4/5. The reasons for canted and perpendicular magnetic structures to form as a result of the competition between the orbitally dependent exchange interactions in different crystallographic directions and the influence of single-ion anisotropy are considered. The mechanism of formation of predominantly noncollinear magnetic structures is shown. Trimer stripe magnetic structures with ordering along pseudo-perovskite axes xp, yp, zp = b are predicted. The presence of magnetic structure components aligned with the b axis is assumed and methods for checking the presence of such components based on field dependencies of magnetization and antiferromagnetic resonance frequencies are proposed.
摘要--本研究致力于对掺杂水平为 x = 3/4、4/5 的电荷有序锰酸盐的非共轭磁结构进行理论分析。研究考虑了由于不同晶体学方向上轨道相关交换相互作用之间的竞争以及单离子各向异性的影响而形成倾斜和垂直磁结构的原因。显示了主要非共线磁性结构的形成机制。预测了沿伪透辉石轴 xp、yp、zp = b 排序的三元条纹磁结构。假定存在与 b 轴对齐的磁结构成分，并提出了基于磁化和反铁磁共振频率的磁场相关性来检查此类成分是否存在的方法。
