Abstract

Spin precession formula is deduced in graphene with Rashba spin-orbit coupling (RSOC) and exchange field, which can control accurately the transmission of up-spin and down-spin electrons. And a wide-angle spin filter can be achieved by the combined effects of exchange field and RSOC. Further spin polarization can be observed, which increases with increasing RSOC or exchange field.
