Ultrafast terahertz spintronics (Conference Presentation)
Author(s): Dmitry Turchinovich

Paper Abstract

In this presentation we will review the spintronic terahertz (THz) phenomena such as ultrafast transient demagnetization [1], generation of spin waves via THz Zeeman torque [2,3], Mott scattering [4], and ultrafast inverse spin-Hall effect [5].
