We investigate the magnetic structures in a bilayer magnetic system with the locally inverted interlayer coupling region using Monte Carlo simulation. Stabilization of multiple magnetic structures including the magnetic skyrmion is possible in the locally inverted interlayer coupling region. Various factors such as the region area, anisotropy, interlayer coupling strength, and exchange coupling strength affects the properties of the structures including its size and chirality. We obtain conditions for their stabilization and for the magnetic structural transitions. Dzyaloshinskii-Moriya interaction (DMI) and the dipolar interaction play a prominent role as they enhance the formation and the stability of structures significantly. An asymmetric feature can arise from the broken inversion symmetry in the structure formation, and it gives an interfacial DMI, which stabilizes the skyrmion. It is realized that the dipole interaction also acts as an effective interfacial DMI in the system.

双层磁系统局部反转层间耦合区中的磁结构

我们使用蒙特卡罗模拟研究了具有局部反转层间耦合区域的双层磁系统中的磁结构。在局部反转的层间耦合区域中，包括磁性斯格明子在内的多个磁性结构的稳定是可能的。区域面积、各向异性、层间耦合强度和交换耦合强度等各种因素影响结构的性质，包括其尺寸和手性。我们获得了它们稳定和磁性结构转变的条件。Dzyaloshinskii-Moriya 相互作用（DMI）和偶极相互作用在显着增强结构的形成和稳定性方面发挥着突出的作用。不对称特征可能是由于结构形成中的反演对称性被破坏，它提供了一个界面 DMI，可以稳定斯格明子。人们认识到偶极相互作用也作为系统中有效的界面 DMI。
