Contact induced spin relaxation in Hanle spin precession measurements
T. Maassen, I. J. Vera-Marun, M. H. D. Guimarães +1
In the field of spintronics the "conductivity mismatch" problem remains an important issue. Here the difference between the resistance of ferromagnetic electrodes and a (high resis…
Enhancement of spin relaxation time in hydrogenated graphene spin valve devices
M. Wojtaszek, I. J. Vera-Marun, T. Maassen +1
Hydrogen adsorbates in graphene are interesting as they are not only strong Coulomb scatterers but they also induce a change in orbital hybridization of the carbon network from sp^…
Localized states influence spin transport in epitaxial graphene
T. Maassen, J. J. van den Berg, E. H. Huisman +4
We developed a spin transport model for a diffusive channel with coupled localized states that result in an effective increase of spin precession frequencies and a reduction of spi…
Spin transport in high quality suspended graphene devices
M. H. D. Guimarães, A. Veligura, P. J. Zomer +4
We measure spin transport in high mobility suspended graphene (μ~ 10^5 cm^2/Vs), obtaining a (spin) diffusion coefficient of 0.1 m^2/s and giving a lower bound on the spin relaxati…
Long spin relaxation times in wafer scale epitaxial graphene on SiC(0001)
T. Maassen, J. J. van den Berg, N. IJbema +4
We developed an easy, upscalable process to prepare lateral spin-valve devices on epitaxially grown monolayer graphene on SiC(0001) and perform nonlocal spin transport measurements…
Intermediate state switching dynamics in magnetic double layer nanopillars grown by molecular beam epitaxy
N. Müsgens, T. Maassen, E. Maynicke +6
We observe a stable intermediate resistance switching state in the current perpendicular to plane geometry for all Co/Cu/Co double layer nanopillar junctions grown by molecular bea…
