Webb19 okt. 2024 · In past decades, ultrafast spin dynamics in magnetic systems have been associated with heat deposition from high energy laser pulses, limiting the selective access to spin order. Here, we use a long wavelength terahertz (THz) pump–optical probe setup to measure structural features in the ultrafast time scale. We find that complete … WebbThe time-dependent THz Kerr signal is composed of a fast electronic response that follows the individual cycles of the electric field and a slow exponential response associated …
Webb1 sep. 2003 · The magneto-optical Kerr effect (MOKE) is a valuable tool in the study of various magnetic properties and electronic structures of materials [4]. Especially the discovery of giant Kerr rotation of about 90° in CeSb created a lot of renewed interest. In a previous report, the optical properties of InSb in THz region were discussed [5].
