Magneto-optical properties of Au upon the injection of hot spin-polarized electrons across Fe/Au(001) interfaces
A. Alekhin, I. Razdolski, M. Berritta +7
We demonstrate a novel method for the excitation of sizable magneto-optical effects in Au by means of the laser-induced injection of hot spin-polarized electrons in Au/Fe/MgO(001)…
Unified theory of magnetization dynamics with relativistic and nonrelativistic spin torques
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
Spin torques play a crucial role in operative properties of modern spintronic devices. To study current-driven magnetization dynamics, spin-torque terms providing the action of spi…
Ultrafast demagnetization of Pt magnetic moment in L1-FePt probed by hard x-ray free electron laser
Kohei Yamamoto, Yuya Kubota, Motohiro Suzuki +15
We demonstrate ultrafast magnetization dynamics in a 5d transition metal using circularly-polarized x-ray free electron laser in the hard x-ray region. A decay time of light-induce…
Generalisation of Gilbert damping and magnetic inertia parameter as a series of higher-order relativistic terms
Ritwik Mondal, Marco Berritta, Peter M. Oppeneer
The phenomenological Landau-Lifshitz-Gilbert (LLG) equation of motion remains as the cornerstone of contemporary magnetisation dynamics studies, wherein the Gilbert damping paramet…
