Charge-transfer-induced 2D ferromagnetism and realization of thermo-remnant memory effect in ultrathin β-NiOOH-encapsulated graphene.

Nanotechnology 2021 Jun 15. Epub 2021 Jun 15.

Research Center for Spin Dynamics and Spin-Wave Devices, Seoul National University, Seoul 151-744, South Korea, Seoul, Korea (the Republic of).

For graphene-based 2D materials, charge transfer at the interface between graphene and ferromagnetic metal leads to many intriguing phenomena. However, because of the unidirectional spin orientation in ferromagnetic transition metals, interface interaction plays a detrimental role in diminishing the magnetic parameters on 2D surfaces. To overcome this issue, we have synthesized ultrathin 2D weak antiferromagnetic β-NiOOH layers on a graphene surface. Read More
