Robust skyrmion-bubble textures in SrRuO thin films stabilized by magnetic anisotropy
arXiv:2001.07039 · doi:10.1103/PhysRevResearch.2.032026
Abstract
Topological spin textures in an itinerant ferromagnet, SrRuO is studied combining Hall transport measurements and numerical simulations. We observe characteristic signatures of the Topological Hall Effect associated with skyrmions. A relatively large thickness of our films and absence of heavy metal layers make the interfacial Dzyaloshinskii-Moriya interaction an unlikely source of these topological spin textures. Additionally, the transport anomalies exhibit an unprecedented robustness to magnetic field tilting and temperature. Our numerical simulations suggest that this unconventional behavior results from magnetic bubbles with skyrmion topology stabilized by magnetodipolar interactions in an unexpected region of parameter space.
