MnBi2Te4 and Bi2Te3 can form natural superlattices, where the MnBi2Te4 layers are separated by multiples of Bi2Te3. The combination of these two materials offers a potential platform for the interplay of tunable magnetism and topology. Here, the authors show that MnBi4Te7 and MnBi6Te10 display a complex magnetic ground state with coexisting ferromagnetic and antiferromagnetic domains.
