Two-dimensional ferromagnetic superlattices.

ABSTRACT: Mechanically exfoliated two-dimensional ferromagnetic materials (2D FMs) possess long-range ferromagnetic order and topologically nontrivial skyrmions in few layers. However, because of the dimensionality effect, such few-layer systems usually exhibit much lower Curie temperature (T _C) compared to their bulk counterparts. It is therefore of great interest to explore effective approaches to enhance their T _C, particularly in wafer-scale for practical applications. Here, we report an interfacial proximity-induced high-T _C 2D FM Fe₃GeTe₂ (FGT) via A-type antiferromagnetic material CrSb (CS) which strongly couples to FGT. A superlattice structure of (FGT/CS)_n, where n stands for the period of FGT/CS h
