Spin absorption by in situ deposited nanoscale magnets on graphene spin valves
Walid Amamou, Gordon Stecklein, Steven J. Koester +2
An in situ measurement of spin transport in a graphene nonlocal spin valve is used to quantify the spin current absorbed by a small (250 nm 750 nm) metallic island. The ex…
Magnetic Proximity Effect in Pt/CoFe2O4 Bilayers
Walid Amamou, Igor V. Pinchuk, Amanda Hanks +8
We observe the magnetic proximity effect (MPE) in Pt/CoFe2O4 bilayers grown by molecular beam epitaxy. This is revealed through angle-dependent magnetoresistance measurements at 5…
Nanosecond spin relaxation times in single layer graphene spin valves with hexagonal boron nitride tunnel barriers
Simranjeet Singh, Jyoti Katoch, Jinsong Xu +5
We present an experimental study of spin transport in single layer graphene using atomic sheets of hexagonal boron nitride (h-BN) as a tunnel barrier for spin injection. While h-BN…
Contact Induced Spin Relaxation in Graphene Spin Valves with Al2O3 and MgO Tunnel Barriers
Walid Amamou, Zhisheng Lin, Jeremiah van Baren +3
We investigate spin relaxation in graphene by systematically comparing the roles of spin absorption, other contact-induced effects (e.g. fringe fields, etc.), and bulk spin relaxat…
Experimental Demonstration of XOR Operation in Graphene Magnetologic Gates at Room Temperature
Hua Wen, Hanan Dery, Walid Amamou +7
We report the experimental demonstration of a magnetologic gate built on graphene at room temperature. This magnetologic gate consists of three ferromagnetic electrodes contacting…
Epitaxial Co-Deposition Growth of CaGe2 Films by Molecular Beam Epitaxy for Large Area Germanane
Igor V. Pinchuk, Patrick M. Odenthal, Adam S. Ahmed +3
Two-dimensional crystals are an important class of materials for novel physics, chemistry, and engineering. Germanane (GeH), the germanium-based analogue of graphane (CH), is of pa…
