When injecting pure spin into chiral materials, direction matters

Researchers from North Carolina State University and the University of Pittsburgh 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.
