Making a ‘sandwich’ out of magnets and topological insulators, potential for lossless electronics

Apr 03, 2022 (Nanowerk News) A Monash University-led research team has discovered that a structure comprising an ultra-thin topological insulator sandwiched between two 2D ferromagnetic insulators becomes a large-bandgap quantum anomalous Hall insulator (Advanced Materials, "Large magnetic gap in a designer ferromagnet–topological insulator–ferromagnet heterostructure"). Such a heterostructure provides an avenue...
