Abstract

Read online

The use of light in driving the magnetization of materials has great technological potential, as well as allowing for insights into the fast dynamics of magnetic systems. Here, the authors combine CrI3, a van der Waals magnet, with WSe2, and demonstrate all optical switching of the resulting heterostructure.
