We have studied the spin-injection properties in epitaxial graphene on SiC. The ferromagnetic metal (FM) electrodes were composed of a tunnel barrier layer AlOx (14 ?) and a ferromagnetic Co (600 ?) layer. We have successfully observed the clear resistance peaks indicating spin-injection both in the ¡°local¡± and ¡°non-local¡± spin measurement set-ups at low temperatures. We estimate spin-injection rate of 1 % based on ¡°non-local¡± measurement and 1.6 % based on local measurements. Spin-injection rate of multilayer graphene by mechanical exfoliation method was twice as high as single layer graphene on SiC based on ¡°local¡± measurement.
