Current-induced magnetization dynamics in single and double layer magnetic nanopillars grown by molecular beam epitaxy
N. Müsgens, E. Maynicke, M. Weidenbach +5
Molecular beam epitaxy is used to fabricate magnetic single and double layer junctions which are deposited in prefabricated nanostencil masks. For all Co | Cu | Co double layer jun…
Spin and charge transport in graphene-based spin transport devices with Co/MgO spin injection and spin detection electrodes
F. Volmer, M. Drögeler, G. Güntherodt +2
In this review we discuss spin and charge transport properties in graphene-based single-layer and few-layer spin-valve devices. We give an overview of challenges and recent advance…
Time-resolved lateral spin-caloric transport of optically generated spin packets in n-GaAs
Stefan Göbbels, Gernot Güntherodt, Bernd Beschoten
We report on lateral spin-caloric transport (LSCT) of electron spin packets which are optically generated by ps laser pulses in the non-magnetic semiconductor n-GaAs at K.…
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…
