Spin Transport and Relaxation in Graphene
Wei Han, K. M. McCreary, K. Pi +5
We review our recent work on spin injection, transport and relaxation in graphene. The spin injection and transport in single layer graphene (SLG) were investigated using nonlocal…
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).…
Epitaxial EuO Thin Films on GaAs
A. G. Swartz, J. Ciraldo, J. J. I. Wong +7
We demonstrate the epitaxial growth of EuO on GaAs by reactive molecular beam epitaxy. Thin films are grown in an adsorption-controlled regime with the aid of an MgO diffusion barr…
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…
Manipulation of Spin Transport in Graphene by Surface Chemical Doping
K. Pi, Wei Han, K. M. McCreary +3
The effects of surface chemical doping on spin transport in graphene are investigated by performing non-local measurements in ultrahigh vacuum while depositing gold adsorbates. We…
