具有非对称界面和垂直磁各向异性的铁磁多层膜可以稳定由于界面Dzyaloshinskiii-Moriya相互作用引起的非平凡磁性结构。由非磁性绝缘间隔物分隔的铁磁层之间的磁性层间耦合是多层膜特性的另一个重要因素。我们解决了由SrIrO 3/SrZrO 3隔离层分隔的铁磁SrRuO 3外延层之间的磁耦合，从而在顶部和底部界面处破坏反转对称性。主要和次要磁化循环使我们能够评估磁耦合的类型和强度。我们推测SrRuO 3多层膜通过非磁性绝缘层（厚度≤1.6 nm）的磁耦合是弱铁磁的，具有非对称界面和垂直磁各向异性的铁磁多层膜可以稳定由于界面Dzyaloshinskiii-Moriya相互作用引起的非平凡磁结构.由非磁性绝缘间隔物分隔的铁磁层之间的磁性层间耦合是多层膜特性的另一个重要因素。我们解决了由SrIrO 3/SrZrO 3隔离层分隔的铁磁SrRuO 3外延层之间的磁耦合，从而在顶部和底部界面处破坏反转对称性。主要和次要磁化循环使我们能够评估磁耦合的类型和强度。我们推测SrRuO 3层通过非磁性绝缘层（厚度≤ 1.6nm）的磁耦合是弱铁磁的。
Ferromagnetic multilayers with asymmetric interfaces and perpendicular magnetic anisotropy can stabilize non-trivial magnetic structures due to interfacial Dzyaloshinskii-Moriya interactions. Magnetic interlayer coupling between ferromagnetic layers separated by non-magnetic insulating spacers is an additional important ingredient for the properties of multilayers. We addressed the magnetic coupling between ferromagnetic SrRuO3 epitaxial layers separated by ultrathin spacers of SrIrO3/SrZrO3, so that inversion symmetry is broken at the top and bottom interfaces. Major and minor magnetization loops allowed us to assess the type and strength of the magnetic coupling. We inferred that the magnetic coupling of SrRuO3 layers through non-magnetic insulating interlayers (≤1.6 nm thick) is weakly ferromagnetic.Ferromagnetic multilayers with asymmetric interfaces and perpendicular magnetic anisotropy can stabilize non-trivial magnetic structures due to interfacial Dzyaloshinskii-Moriya interactions.
