Natural superlattice structures $(\mathrm{MnB}{\mathrm{i}}_2\mathrm{T}{\mathrm{e}}_4)(\mathrm{B}{\mathrm{i}}_2\mathrm{T}{\mathrm{e}}_3)$${}_n$ ($n$ = 1, 2,...), in which magnetic $\mathrm{MnB}{\mathrm{i}}_2\mathrm{T}{\mathrm{e}}_4$ layers are separated by nonmagnetic $\mathrm{B}{\mathrm{i}}_2\mathrm{T}{\mathrm{e}}_3$ layers,…
