Ultrafast spin-to-charge conversions of antiferromagnetic (111)-oriented L1_2-Mn_3Ir
arxiv(2023)
摘要
Antiferromagnetic L1_2-Mn_3Ir combines outstanding spin-transport properties with magnons in the terahertz (THz) frequency range. However, the THz radiation emitted by ultrafast spin-to-charge conversion via the inverse spin Hall effect remains unexplored. In this study, we measured the THz emission and transmission of a permalloy/(111)-oriented L1_2-Mn_3Ir multilayer by THz time-domain spectroscopy. The spin Hall angle was determined to be approximately constant at 0.024 within a frequency range of 0.3-2.2 THz, in comparison with the THz spectroscopy of a permalloy/Pt multilayer. Our results not only demonstrate the potential of L1_2-Mn_3Ir as a spintronic THz emitter but also provide insights into the THz spin transport properties of L1_2-Mn_3Ir.
