Anatomy and giant enhancement of the perpendicular magnetic anisotropy of cobalt-graphene heterostructures
Hongxin Yang, Anh Duc Vu, Ali Hallal +5
We report strongly enhanced perpendicular magnetic anisotropy (PMA) of Co films by graphene coating from both first-principles and experiments. Our calculations show that graphene…
Origin of interfacial perpendicular magnetic anisotropy in MgO/CoFe/metallic capping layer structures
Shouzhong Peng, Mengxing Wang, Hongxin Yang +9
Spin-transfer-torque magnetic random access memory (STT-MRAM) attracts extensive attentions due to its non-volatility, high density and low power consumption. The core device in ST…
Anatomy of Dzyaloshinskii-Moriya Interaction at Co/Pt Interfaces
Hongxin Yang, André Thiaville, Stanislas Rohart +2
The Dzyaloshinskii-Moriya Interaction (DMI) between spins is induced by spin-orbit coupling in magnetic materials lacking inversion symmetry. DMI is recognized to play a crucial ro…
