Room temperature weak ferromagnetism in Sn1-xMnxSe2 2D films grown by molecular beam epitaxy.

We discuss growth and magnetic properties of high-quality two dimensional (2D) Sn_1-xMn_xSe₂ films. Thin films of this 2D ternary alloy with a wide range of Mn concentrations were successfully grown by molecular beam epitaxy. Mn concentrations up to x ≈ 0.60 were achieved without destroying the crystal structure of the parent SnSe₂ 2D system. Most important, the specimens show clear weak ferromagnetic behavior above room temperature, which should be of interest for 2D spintronic applications. [ABSTRACT FROM AUTHOR]
