Stacking-Dependent Magnetism in Bilayer CrI3
TLDR
In this paper, the authors reported the connection between the stacking order and magnetic properties of bilayer CrI3 using first-principles calculations and showed that stacking order defines the magnetic ground state.Abstract:
We report the connection between the stacking order and magnetic properties of bilayer CrI3 using first-principles calculations. We show that the stacking order defines the magnetic ground state. By changing the interlayer stacking order, one can tune the interlayer exchange interaction between antiferromagnetic and ferromagnetic. To measure the predicted stacking-dependent magnetism, we propose using linear magnetoelectric effect. Our results not only gives a possible explanation for the observed antiferromagnetism in bilayer CrI3 but also have direct implications in heterostructures made of two-dimensional magnets.read more
