Ultrafast Magnetization Reversal by Picosecond Electrical Pulses
Yang Yang, R. B. Wilson, Jon Gorchon +3
The field of spintronics involves the study of both spin and charge transport in solid state devices with a view toward increasing their functionality and efficiency. Alternatively…
Electron-phonon interaction during optically induced ultrafast magnetization dynamics of Au/GdFeCo bilayers
Richard B Wilson, Charles-Henri Lambert, Jon Gorchon +3
The temperature evolution of GdFeCo electrons following optical heating plays a key role in all optical switching of GdFeCo and is primarily governed by the strength of coupling be…
Ultrafast Magnetic Switching of GdFeCo with Electronic Heat Currents
R. B. Wilson, Jon Gorchon, Yang Yang +3
We report the magnetic response of Au/GdFeCo bilayers to optical irradiation of the Au surface. For bilayers with Au thickness greater than 50 nm, the great majority of energy is a…
Electric Current Induced Ultrafast Demagnetization
R. B. Wilson, Yang Yang, Jon Gorchon +3
We report the magnetic response of Co/Pt multilayers to picosecond electrical heating. Using photoconductive Auston switches, we generate electrical pulses with 5.5 picosecond dura…
The role of electron and phonon temperatures in the helicity-independent all-optical switching of GdFeCo
Jon Gorchon, Richard B. Wilson, Yang Yang +6
Ultrafast optical heating of the electrons in ferrimagnetic metals can result in all-optical switching (AOS) of the magnetization. Here we report quantitative measurements of the t…
Model for multi-shot all-thermal all-optical switching in ferromagnets
Jon Gorchon, Yang Yang, Jeffrey Bokor
All optical magnetic switching (AOS) is a recently observed rich and puzzling phenomenon that offers promis- ing technological applications. However, fundamental understanding of t…
