Transition metal dichalcogenides (TMDs, MX₂: M=Nb, Ti, V..., X = S, Se, Te...) are a familiy of two-dimensional (2D) layered materials that attract great attention because of their large landscape of collective phenomena that differ from the bulk ones. Among them, magnetism in low dimensions has been argued for decades, being rejected by the Mermin-Wagner theorem but found as Ising-type ferromagnets in purely 2D-materials VSe₂ is a TMDs where ferromagnetism is present in its normal state (NS) bulk phase, but becomes supressed when the charge density wave (CDW) phase 4 × 4 × 3 appears or it is reduced to the monolayer limit. Here, we present a computational study of several heterostructure packaging of VSe₂ with other TMDs materials in order to elucidate if the formation of the CDW can be supressed by different stacking arrangements, and if with these stackings we are able to retain magnetism in the system.
