Abstract

Understanding and controlling the magnetization dynamics on the femtosecond timescale is becoming indispensable both at the fundamental level and to develop future technological applications. While direct laser excitation of a ferromagnetic layer was commonly used during the past twenty years, laser induced hot-electrons femtosecond pulses and subsequent transport in magnetic multilayers has attracted a lot of attention. Indeed, replacing photons by hot-electrons offers complementary information to improve our understanding of ultrafast magnetization dynamics and to provide new possibilities for manipulating the magnetization in a thin layer on the femtosecond timescale. In this review, we report on experiments of hot-electrons induced ultrafast magnetic phenomena. We discuss the role of hot-electrons transport in the ultrafast loss of magnetization in magnetic single and multilayers and how it is exploited to trigger magnetization dynamics in magnetic multilayers.
