Contact-induced charge contributions to non-local spin transport measurements in Co/MgO/graphene devices
F. Volmer, M. Drögeler, T. Pohlmann +3
Recently, it has been shown that oxide barriers in graphene-based non-local spin-valve structures can be the bottleneck for spin transport. The barriers may cause spin dephasing du…

Suppression of contact-induced spin dephasing in graphene/MgO/Co spin-valve devices by successive oxygen treatments
F. Volmer, M. Drögeler, E. Maynicke +5
By successive oxygen treatments of graphene non-local spin-valve devices we achieve a gradual increase of the contact resistance area products () of Co/MgO spin injection and…

Nanosecond spin lifetimes in single- and few-layer graphene-hBN heterostructures at room temperature
Marc Drögeler, Frank Volmer, Maik Wolter +6
We present a new fabrication method of graphene spin-valve devices which yields enhanced spin and charge transport properties by improving both the electrode-to-graphene and graphe…
