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…
Differentiating Contributions of Electrons and Phonons to the Thermoreflectance Spectra of Gold
Kexin Liu, Xinping Shi, Frank Angeles +4
To better understand the many effects of temperature on the optical properties of metals, we experimentally and theoretically quantify the electron vs. phonon contributions to the…
Unifying femtosecond and picosecond single-pulse magnetic switching in GdFeCo
Florian Jakobs, Thomas Ostler, Charles-Henri Lambert +6
Many questions are still open regarding the physical mechanisms behind the magnetic switching in GdFeCo alloys by single optical pulses. Phenomenological models suggest a femtoseco…
Picosecond Spin Orbit Torque Switching
Kaushalya Jhuria, Julius Hohlfeld, Akshay Pattabi +13
Reducing energy dissipation while increasing speed in computation and memory is a long-standing challenge for spintronics research. In the last 20 years, femtosecond lasers have em…
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…
