|Title:||Enhancement of spin injection from ferromagnet to graphene with a Cu interfacial layer|

|Abstract:||We present an enhancement in spin injection from ferromagnet to multilayer graphene through the introduction of a thin Cu interfacial layer at the metal-graphene interface. A nonlocal magnetoresistance of 286 m and a corresponding spin-injection efficiency of 2.46 have been obtained which are among the highest values reported so far for metal-contacted graphene spin-valve devices. The enhancement of spin-injection is attributed to a non-ohmic contact between Cu and graphene, as revealed by the temperature-dependent I-V and differential conductance measurements. © 2012 American Institute of Physics.|
