Researchers study the importance of direction when injecting pure spin into chiral materials
Researchers at North Carolina State University, University of Pittsburgh, University of Illinois at Urbana-Champaign, Chinese Academy of Sciences and Beijing Normal University have studied how the spin information of an electron, called a pure spin current, moves through chiral materials.
They found that the direction in which the spins are injected into chiral materials affects their ability to pass through them. These chiral “gateways” could be used to design energy-efficient spintronic devices for data storage, communication and computing.
