Abstract
Advanced magnetic tunneling junctions (MTJs) that dramatically reduce power consumption (switching energy, ESW) while maintaining a reasonably high tunneling magnetoresistance (on/off ratio, TMR) and strong thermal stability at room temperature are described herein. The MTJs include a magnetic insulator, such as an antiferromagnetic material, as the tunnel barrier. A more energy efficient switching in the MTJs is achieved by magnon assisted switching.
