When injecting pure spin into chiral materials, direction matters

"move spin information through material without having to move associated charge, saving energy... success depends on angle between spin polarization and chiral axis... 2 equally effective methods inject pure spin into 2 chiral cobalt oxide thin films, each with different chirality: microwave particle excitation and ultrafast laser heating... when pure spin aligned either parallel or anti-parallel to chiral axis, its ability to pass through material improved 3000%... energy-efficient spintronic devices for data storage, communication, computing"
