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…
TiO2 as an electrostatic template for epitaxial growth of EuO on MgO(001) by reactive molecular beam epitaxy
A. G. Swartz, Jared J. I. Wong, I. V. Pinchuk +1
We investigate the initial growth modes and the role of interfacial electrostatic interactions of EuO epitaxy on MgO(001) by reactive molecular beam epitaxy. A TiO2 interfacial lay…
Electric Field Control of the Verwey Transition and Induced Magnetoelectric Effect in Magnetite
Jared J. I. Wong, Adrian G. Swartz, Renjing Zheng +2
We incorporate single crystal FeO thin films into a gated device structure and demonstrate the ability to control the Verwey transition with static electric fields. The Ver…
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…

Tailoring Interlayer Exchange Coupling of Ferromagnetic Films Across MgO with Fe Nanoclusters
Jared J. I. Wong, Luciana Ramirez, A. G. Swartz +4
We investigate the interlayer exchange coupling in Fe/MgO/Fe and Fe/MgO/Co systems with magnetic Fe nanoclusters embedded in the MgO spacer. Samples are grown by molecular beam epi…
Probing Magnetic Configurations in Co/Cu Multilayered Nanowires
Jared Wong, Peter Greene, Randy K. Dumas +1
Magnetic configurations in heterostructures are often difficult to probe when the magnetic entities are buried inside. In this study we have captured magnetic and magnetoresistance…
