Magnetic field dependence of the magnon spin diffusion length in the magnetic insulator yttrium iron garnet
L. J. Cornelissen, B. J. van Wees
We investigated the effect of an external magnetic field on the diffusive spin transport by magnons in the magnetic insulator yttrium iron garnet (YIG), using a non-local magnon tr…
Towards the understanding of the origin of charge-current-induced spin voltage signals in the topological insulator BiSe
E. K. de Vries, A. M. Kamerbeek, N. Koirala +5
Topological insulators provide a new platform for spintronics due to the spin texture of the surface states that are topologically robust against elastic backscattering. Here, we r…
Spin-Hall magnetoresistance and spin Seebeck effect in spin-spiral and paramagnetic phases of multiferroic CoCr2O4 films
Aisha Aqeel, Nynke Vlietstra, Jeroen A. Heuver +4
We report on the spin-Hall magnetoresistance (SMR) and spin Seebeck effect (SSE) in multiferroic CoCr2O4 (CCO) spinel thin films with Pt contacts. We observe a large enhancement of…
Spin Relaxation in Graphene with self-assembled Cobalt Porphyrin Molecules
S. Omar, M. Gurram, I. J. Vera-Marun +5
In graphene spintronics, interaction of localized magnetic moments with the electron spins paves a new way to explore the underlying spin relaxation mechanism. A self-assembled lay…
24 \textmu m length spin relaxation length in boron nitride encapsulated bilayer graphene
Josep Ingla-Aynés, Marcos H. D. Guimarães, Rick J. Meijerink +2
We have performed spin and charge transport measurements in dual gated high mobility bilayer graphene encapsulated in hexagonal boron nitride. Our results show spin relaxation leng…
Comparison of the magneto-Peltier and magneto-Seebeck effects in magnetic tunnel junctions
J. Shan, F. K. Dejene, J. C. Leutenantsmeyer +3
Understanding heat generation and transport processes in a magnetic tunnel junction (MTJ) is a significant step towards improving its application in current memory devices. Recent…
