Title: Strain-Induced Tunable Magnetic Interaction in (Mo,Co)S{sub 2}/(Si,Co)C Heterostructure

Abstract

Using the first-principles method, we reported tunable magnetic interaction in Co-doped MoS{sub 2}/SiC van der Waals (vdW) heterostructures under normal strain. The interlayer interaction between (Mo,Co)S{sub 2} and (Si,Co)C monolayers is antiferromagnetic (AFM) at the equilibrium state. Our results reveal that the compressive strain has much influence on the interlayer interaction of the vdW heterostructures and the interlayer interaction switched from AFM to ferromagnetic (FM). By contrast, under a tensile strain, the interlayer interaction between (Mo,Co)S{sub 2} and (Si,Co)C monolayers is always AFM. The results show that the interaction between (Mo,Co)S{sub 2} and (Si,Co)C monolayers changes from AFM to FM, which could be explained by the superexchange and the p − d exchange, respectively. Moreover, according to the magnetic anisotropy energy (MAE), the easy axis of the magnetization is parallel to the a-axis in current vdW heterostructures.
