Long Distance Spin Transport in High Mobility Graphene on Hexagonal Boron Nitride
P. J. Zomer, M. H. D. Guimarães, N. Tombros +1
We performed spin transport measurements on boron nitride based single layer graphene devices with mobilities up to 40 000 cmVs. We could observe spin transport…
Platinum thickness dependence of the inverse spin-Hall voltage from spin pumping in a hybrid YIG/Pt system
Vincent Castel, Nynke Vlietstra, Jamal Ben Youssef +1
We show the first experimental observation of the platinum (Pt) thickness dependence in a hybrid YIG/Pt system of the inverse spin-Hall effect from spin pumping, over a large frequ…
Frequency and power dependence of spin-current emission by spin pumping in a thin film YIG/Pt system
Vincent Castel, Jamal Ben Youssef, Nynke Vlietstra +1
This paper presents the frequency dependence of the spin current emission in a hybrid ferrimagnetic insulator/normal metal system. The system is based on a ferrimagnetic insulating…
Spin-dependent Seebeck coefficients of Ni_{80}Fe_{20} and Co in nanopillar spin valves
F. K. Dejene, J. Flipse, B. J. van Wees
We have experimentally determined the spin-dependent Seebeck coefficient of permalloy (Ni_{80}Fe_{20}) and cobalt (Co) using nanopillar spin valve devices. The devices were specifi…
Reversible hydrogenation and band gap opening of graphene and graphite surfaces probed by scanning tunneling spectroscopy
Andres Castellanos-Gomez, Magdalena Wojtaszek, Arramel +2
The effect of hydrogenation on the topography and the electronic properties of graphene and graphite surfaces are studied by scanning tunneling microscopy and spectroscopy. The sur…
Transport Gap in Suspended Bilayer Graphene at Zero Magnetic Field
A. Veligura, H. J. van Elferen, N. Tombros +3
We report a change of three orders of magnitudes in the resistance of a suspended bilayer graphene flake which varies from a few ks in the high carrier density regime to several…
