Multielemental single-atom-thick <i>A</i> layers in nanolaminated V₂(Sn, <i>A</i>) C (<i>A</i> = Fe, Co, Ni, Mn) for tailoring magnetic properties.

ABSTRACT: Tailoring of individual single-atom-thick layers in nanolaminated materials offers atomic-level control over material properties. Nonetheless, multielement alloying in individual atomic layers in nanolaminates is largely unexplored. Here, we report 15 inherently nanolaminated V₂(A _xSn_1-x)C (A = Fe, Co, Ni, Mn, and combinations thereof, with x ∼ 1/3) MAX phases synthesized by an alloy-guided reaction. The simultaneous occupancy of the 4 magnetic elements and Sn in the individual single-atom-thick A layers constitutes high-entropy MAX phase in which multielemental alloying exclusively occurs in the 2-dimensional (2D) A layers. V₂(A _xSn_1-x)C exhibit distinct ferromagnetic behavior that can be compositionall
