Description:

In low-dimensional correlated materials, the formation and the evolution of magnetic domains are particularly complex. Despite the large amount of studies, however, there are still open challenges regarding the nature of magnetic domains phase and the formation mechanism of domain boundaries, especially toward the limit of monolayer films. It becomes more complicated when considering materials which are marked by non-trivial topological properties since the domain walls can host topologically protected electronic states. In this context, the SrRuO3 is an ideal platform to explore the correlation between magnetic domains and topological properties since the emergent topological features have been discussed in the past in this system. In my talk, I will be focusing on the structure of magnetic domains in ultrathin SrRuO3 where we observed a robust magnetic stripy state and a modulation of current flow associated with this domain pattern. I will discuss the results in the vicinity of the role of the strain in pinning the magnetization direction and the topologically protected edge channels at the domain boundaries.
