论文摘要
研究了大厅运输测量和数值模拟，研究了流动的铁磁体中的拓扑旋转纹理。我们观察到与天空相关的拓扑厅效应的特征特征。我们的胶片的厚度相对较大，并且没有重金属层的缺乏使界面的dzyaloshinskii-moriya相互作用是这些拓扑自旋纹理的不可能来源。此外，转运异常对磁场倾斜和温度表现出前所未有的鲁棒性。我们的数值模拟表明，这种非常规的行为是由于在参数空间的意外区域内通过磁性相互作用稳定的磁性气泡引起的。
Topological spin textures in an itinerant ferromagnet, SrRuO$_3$ 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.
