Phonon modes and Raman signatures of MnBi_{2n}Te_{3n+1}(n=1,2,3,4) magnetic topological heterostructures

Phonon modes and Raman signatures of MnBi_{2n}Te_{3n+1}(n=1,2,3,4) magnetic topological heterostructures

An intrinsic antiferromagnetic topological insulator MnBi_{2}Te_{4} arises when intercalating a Mn-Te bilayer chain in a topological insulator, Bi_{2}Te_{3}. We present observations on the inter- and intralayer phonon modes of the generalized MnBi_{2n}Te_{3n+1}(n=1,2,3,4) family using cryogenic low-...
