We demonstrate spin injection into a graphene thin film with high reliability by using non-local magnetoresistance (MR) measurements, in which the electric current path is completely separated from the spin current path. Using these non-local measurements, an obvious MR effect was observed at room temperature; the MR effect was ascribed to magnetization reversal of ferromagnetic electrodes. This result is a direct demonstration of spin injection into a graphene thin film. Furthermore, this is…

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

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

Spin injection properties in trilayer graphene lateral spin valves

We report on the electrical injection and detection of spin accumulation in trilayer-graphene/MgO/Permalloy lateral spin-valve (LSV) structure. Non-local spin valve signal is clearly observed in the

Spin transport in graphite and graphene spin valves

Spin transport in graphene devices has been investigated in both local and non-local spin valve geometries. In the nonlocal measurement, spin transport and spin precession in single layer and bilayer

We demonstrate charge and spin current transport in a graphene-based lateral spin valve using yttrium oxide (Y-O) as a tunneling barrier between graphene and a ferromagnetic electrode. A Y-O layer

Gate control of spin transport in multilayer graphene

We experimentally studied the gate voltage dependence of spin transport in multilayer graphene (MLG) using the nonlocal spin detection technique. We found that the spin signal is a monotonically

We report the gate-voltage dependence of the spin transport in multilayer graphene (MLG) studied experimentally by the local measurement. The sample consists of a Ni/MLG/Ni junction, where the
