WebMay 12, 2012 · We have investigated the ultrafast spin dynamics in EuO thin films by time-resolved Faraday rotation spectroscopy. The photoinduced magnetization is found to be increased in a transient manner, accompanied with subsequent demagnetization. The dynamical magnetization enhancement showed a maximum slightly below the Curie … WebJul 12, 2011 · We use time-resolved Faraday rotation spectroscopy to probe the electron spin dynamics in ZnO and magnetically doped Zn 1–x Co x O sol–gel thin films. In undoped ZnO, we observe an anomalous temperature dependence of the ensemble spin dephasing time T 2 *, i.e., longer coherence times at higher temperatures, reaching T 2 * ∼ 1.2 ns at …

WebCavity ring-down Faraday rotation spectroscopy (CRD-FRS) is a technique for trace gas measurements of paramagnetic species that retrieves the molecular concentration from the polarization rotation measured as the difference between simultaneously recorded ring-down times of two orthogonal polarization states. The differential measurement is … WebOct 5, 2024 · I am a quantum chemist with a deep passion for the interaction of light and matter. My research addresses the theoretical description and simulation of light-induced excitations and subsequent dynamics of atoms and molecules as well as the simulation of novel time-resolved experiments that can be used to track chemical reactions and the … WebMar 21, 2012 · Time-resolved Faraday rotation spectroscopy is used to study the electron spin coherence in colloidal CdS quantum dots. Long-lived spin coherence with dephasing time T 2 * > 3 ns has been found at room temperature.
