Probing and controlling magnetic states in 2D layered magnetic materials
Invited
Abstract
Controlling magnetism by electrical means is a key challenge to better information technology. Electrical control of magnetic states has been explored in a variety of materials including dilute magnetic semiconductors, ferromagnetic metal thin films and multiferroics. The recently emerged two-dimensional (2D) layered magnetic materials provide unprecedented opportunities to study magnetism in the 2D limit and engineer devices for electrical control through the van der Waals heterostructures. In this talk, I will discuss our recent results on probing the spins, their fluctuations and dynamics in 2D transition metal trihalides. I will also discuss about how to tune these properties by either a pure electric field or electrostatic doping and the possible physical mechanisms for the observed effects.
