▲ [9p-Z23-2] [INVITED] Terahertz spectroscopy for dynamics in Dirac and Weyl semimetals toward high-speed electronics and spintronics
Keywords:terahertz, Dirac semimetal, Weyl semimetal
We also report observation of the THz anomalous Hall effect in a Mn3Sn thin film by a broadband polarization-resolved THz spectroscopy up to 6 THz. The large THz response in the antiferromagnets depending on the spin order paves the way for ultrafast readout of magnetism with THz current on device.
