Аннотация: MnBi₂Te₄, Mn(Bi,Sb)₂Te₄, and MnBi₂Te₄(Bi₂Te₃)_<i>m</i> (<i>m</i> ≥ 1) are assigned to magnetic topological insulators. Successful application of these materials in nanoelectronic devices calls for comprehensive investigation of their electronic structure and magnetic properties in dependence of the Bi/Sb atomic ratio and the number <i>m</i> of Bi₂Te₃ blocks. The magnetic properties of the surface of MnBi₂Te₄, MnBi₄Te₇, and Mn(Bi$_{{1-x}}$Sb_<i>x</i>)₂Te₄ compounds (<i>x</i> = 0.43 and 0.32) have been studied using the magneto-optical Kerr effect. It is shown that the temperatures of magnetic transitions on the surface and in the bulk of MnBi₄Te₇ and Mn(Bi, Sb)₂Te₄ differ significantly.
