Abstract: Systematic studies of magneto-transport properties of the whole (MnBi$_2$Te$_4$)(Bi$_2$Te$_3)_m$ family of magnetic topological insulators $(m = 0,1,...,6)$ have been carried out. Temperature dependences of the resistivity, magnetoresistance and the Hall effect at low temperatures have been studied. When m increases, i.e., when the separation between 2D MnBi$_2$Te$_4$ magnetic layers becomes larger, the transition from antiferromagnetic to ferromagnetic state takes place. We have found that ferromagnetic state survives even in the samples with $m = 6$, when 2D magnets are separated by six non-magnetic Bi$_2$Te$_3$ blocks.
