Discovery of terahertz-frequency orbitally-coupled magnons in a kagome ferromagnet
Mengqian Che, Weizhao Chen, Maoyuan Wang +12
In ferromagnetic materials, magnons - quanta of spin waves - typically resonate in the gigahertz range. Beyond conventional magnons, while theoretical studies have predicted magnon…
Real-time observation of magnetization and magnon dynamics in a two-dimensional topological antiferromagnet MnBi2Te4
F. Michael Bartram, Meng Li, Liangyang Liu +9
Atomically thin van der Waals magnetic materials have not only provided a fertile playground to explore basic physics in the two-dimensional (2D) limit but also created vast opport…
Ultrafast coherent interlayer phonon dynamics in atomically thin layers of MnBi2Te4
F. Michael Bartram, Yu-Chen Leng, Yongchao Wang +10
The atomically thin MnBi2Te4 crystal is a novel magnetic topological insulator, exhibiting exotic quantum physics. Here we report a systematic investigation of ultrafast carrier dy…
Anomalous Kerr Effect in SrRuO Thin Films
F. Michael Bartram, Sopheak Sorn, Zhuolu Li +7
We study the magneto-optical Kerr effect (MOKE) in SrRuO thin films, uncovering wide regimes of wavelength, temperature, and magnetic field where the Kerr rotation is not simpl…
Electric-field Control of Magnetism with Emergent Topological Hall Effect in SrRuO3 through Proton Evolution
Zhuolu Li, Shengchun Shen, Zijun Tian +16
Ionic substitution forms an essential pathway to manipulate the carrier density and crystalline symmetry of materials via ion-lattice-electron coupling, leading to a rich spectrum…
