Integrating MBE materials with graphene to induce novel spin-based phenomena
Adrian G. Swartz, Kathleen M. McCreary, Wei Han +8
Magnetism in graphene is an emerging field that has received much theoretical attention. In particular, there have been exciting predictions for induced magnetism through proximity…
Effect of in-situ deposition of Mg adatoms on spin relaxation in graphene
Adrian G. Swartz, Jen-Ru Chen, Kathleen M. McCreary +3
We have systematically introduced charged impurity scatterers in the form of Mg adsorbates to exfoliated single layer graphene and observe little variation of the spin relaxation t…
Spin Relaxation in Single Layer Graphene with Tunable Mobility
Wei Han, Jen-Ru Chen, Deqi Wang +5
Graphene is an attractive material for spintronics due to theoretical predictions of long spin lifetimes arising from low spin-orbit and hyperfine couplings. In experiments, howeve…
Magnetic Moment Formation in Graphene Detected by Scattering of Pure Spin Currents
Kathleen M. McCreary, Adrian G. Swartz, Wei Han +2
Hydrogen adatoms are shown to generate magnetic moments inside single layer graphene. Spin transport measurements on graphene spin valves exhibit a dip in the non-local spin signal…
Oscillatory Spin Polarization and Magneto-Optic Kerr Effect in Fe3O4 Thin Films on GaAs(001)
Yan Li, Wei Han, A. G. Swartz +5
The spin dependent properties of epitaxial Fe3O4 thin films on GaAs(001) are studied by the ferromagnetic proximity polarization (FPP) effect and magneto-optic Kerr effect (MOKE).…
Tunneling Spin Injection into Single Layer Graphene (Supplementary Information)
Wei Han, K. Pi, K. M. McCreary +4
We achieve tunneling spin injection from Co into single layer graphene (SLG) using TiO2 seeded MgO barriers. A non-local magnetoresistance (ΔRNL) of 130 Ω is observed at room tempe…
