Magnetic tunnel junctions consist of two magnetic layers, separated by a thin insulator. The simplicity belies the industrial importance: magnetic tunnel junctions have a very wide variety of applications in contemporary society. Here, Fu et al present a magnetic tunnel junction composed of single van der Waals magnetic insulator, CrI3, exhibiting remarkably low power consumption.
