Electron-Phonon Scattering governs both Ultrafast and Precessional Magnetization Dynamics in Co-Fe Alloys

Ramya Mohan, Victor H. Ortiz, Luat Vuong +2

Recent investigations have advanced the understanding of how structure-property relationships in ferromagnetic metal alloys affect the magnetization dynamics on nanosecond time-sca…

Ultrafast Measurements of the Interfacial Spin Seebeck Effect in Au and Rare-Earth Iron Garnet Bilayers

Victor H. Ortiz, Michael J. Gomez, Yawen Liu +3

We investigate picosecond spin-currents across Au/iron-garnet interfaces in response to ultrafast laser heating of the electrons in the Au film. In the picoseconds after optical he…

Parametric dependence of hot electron relaxation timescales on electron-electron and electron-phonon interaction strengths

Richard Wilson, Sinisa Coh

Understanding how photoexcited electron dynamics depend on electron-electron (e-e) and electron-phonon (e-p) interaction strengths is important for many fields, e.g. ultrafast magn…
