Room-Temperature Terahertz Anomalous Hall Effect in Weyl Antiferromagnet MnSn Thin Films
Takuya Matsuda, Natsuki Kanda, Tomoya Higo +3
Antiferromagnetic spin motion at terahertz (THz) frequencies attracts growing interests for fast spintronics, however their smaller responses to external field inhibit device appli…

Efficient Terahertz Harmonic Generation with Coherent Acceleration of Electrons in the Dirac Semimetal Cd3As2
Bing Cheng, Natsuki Kanda, Tatsuhiko N. Ikeda +7
We report strong terahertz (~10^12 Hz) high harmonic generation in thin films of Cd3As2, a three-dimensional Dirac semimetal at room temperature. The third harmonics is detectable…
