Dirac-Surface-State Modulated Spin Dynamics in a Ferrimagnetic Insulator at Room Temperature
Chi Tang, Qi Song, Cui-Zu Chang +10
This work demonstrates dramatically modified spin dynamics of magnetic insulator (MI) by the spin-momentum locked Dirac surface states of the adjacent topological insulator (TI) wh…

Crystal Structure Manipulation of the Exchange Bias in an Antiferromagnetic Film
Wei Yuan, Tang Su, Qi Song +8
Exchange bias is one of the most extensively studied phenomena in magnetism, since it exerts a unidirectional anisotropy to a ferromagnet (FM) when coupled to an antiferromagnet (A…

Experimental Investigation of Temperature-Dependent Gilbert Damping in Permalloy Thin Films
Yuelei Zhao, Qi Song, See-Hun Yang +5
The Gilbert damping of ferromagnetic materials is arguably the most important but least understood phenomenological parameter that dictates real-time magnetization dynamics. Unders…
