我们研究了垂直磁化的Pt/Co/Ir薄膜的磁性，并研究了确定超薄膜中界面Dzyaloshinskiii-Moriya（DM）相互作用的畴壁蠕变方法。测量的Co层厚度的饱和磁化强度，垂直磁各向异性，对称和反对称（即DM）的交换能在Pt/Co/Ir薄膜的依赖性已确定这些属性之间的关系。我们讨论了测量的DM相互作用的畴壁蠕变制度的反向畴的扩展。我们展示了蠕变参数如何表现为面内偏置场的函数，并讨论了畴壁粗糙度对测量畴扩展的DM相互作用的影响。而修正的蠕变定律DM场和面内偏置场已考虑到的变化的能量势垒标度参数$alpha$，我们发现，$alpha$和速度标度参数$v_{0}$的变化作为面内偏置场的函数。
We study the magnetic properties of perpendicularly magnetised Pt/Co/Ir thin films and investigate the domain wall creep method of determining the interfacial Dzyaloshinskii-Moriya (DM) interaction in ultra-thin films. Measurements of the Co layer thickness dependence of saturation magnetisation, perpendicular magnetic anisotropy, and symmetric and antisymmetric (i.e. DM) exchange energies in Pt/Co/Ir thin films have been made to determine the relationship between these properties. We discuss the measurement of the DM interaction by the expansion of a reverse domain in the domain wall creep regime. We show how the creep parameters behave as a function of in-plane bias field and discuss the effects of domain wall roughness on the measurement of the DM interaction by domain expansion. Whereas modifications to the creep law with DM field and in-plane bias fields have taken into account changes in the energy barrier scaling parameter $alpha$, we find that both $alpha$ and the velocity scaling parameter $v_{0}$ change as a function of in-plane bias field.
