Observation and Control of Chiral Spin Frustration in BiYIG Thin Films
Jinlong Wang, Hanchen Wang, Zhewen Xu +17
Chiral interactions within magnetic layers stabilize the formation of noncollinear spin textures, which can be leveraged to design devices with tailored magnetization dynamics. Her…
Minimizing sensor-sample distances in scanning nitrogen-vacancy magnetometry
Zhewen Xu, Marius L. Palm, William S. Huxter +10
Scanning magnetometry with nitrogen-vacancy (NV) centers in diamond has led to significant advances in the sensitive imaging of magnetic systems. The spatial resolution of the tech…
Giant Topological Hall Effect Across Wide Temperature in Pt/NiCo2O4 Heterostructure
Bharat Giri, Ahsan Ullah, Jing Li +10
Topological Hall effect (THE), a quantum phenomenon arising from emergent magnetic field generated by topological spin texture, is a key method for detecting non-coplanar spin stru…
Observation of chiral domain walls in an octupole-ordered antiferromagnet
Moeta Tsukamoto, Zhewen Xu, Tomoya Higo +10
Spin chirality in antiferromagnets offers new opportunities for spintronics. The kagome antiferromagnet Mn3Sn is a paradigmatic material in which the antiferromagnetic order parame…
