· JVASP-82132· MnBi2Te4

MnBi2Te4 is a layered ternary compound belonging to the topological insulator family, composed of manganese, bismuth, and tellurium. This is a research-stage material currently under active investigation for its unique electronic and magnetic properties rather than established industrial production. Engineers and researchers are exploring it for next-generation spintronic and topological electronic devices where its inherent magnetic ordering combined with topological surface states could enable novel quantum phenomena and ultralow-power switching applications.
