Energy-efficient picosecond spin-orbit torque magnetization switching in ferro- and ferrimagnetic films
Eva DÃaz, Alberto Anadón, Pablo Olleros-RodrÃguez +7
Electrical current pulses can be used to manipulate magnetization efficiently via spin-orbit torques (SOTs). Pulse durations as short as a few picoseconds have been used to switch…

Quartic scaling of sound attenuation with frequency in vitreous silica
P. -J. Wang, A. Huynh, T. -C. Hung +8
Many theories predict a quartic acoustic attenuation increase at sub-THz frequencies in glassy media for the excess vibrational modes known as the boson peak anomaly. Here by intro…
