Giant magnon spin conductivity in ultrathin yttrium iron garnet films
Autor: X.-Y. Wei, O. Alves Santos, C. H. Sumba Lusero, G. E. W. Bauer, J. Ben Youssef, B. J. van Wees
Publikováno v: Nature Materials, 21(12), 1352-1356. Nature Publishing Group
Conductivities are key material parameters that govern various types of transport (electronic charge, spin, heat and so on) driven by thermodynamic forces. Magnons, the elementary excitations of the magnetic order, flow under the gradient of a magnon

Bias induced up to 100% spin-injection and detection polarizations in ferromagnet/bilayer-hBN/graphene/hBN heterostructures
Autor: M. Gurram, S. Omar, B. J. van Wees
Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)
In 2D spin-valve devices, effective spin injection and detection can be potentially realised combining graphene with an ideal hBN tunnel barrier. Here, the authors report that a bilayer hBN tunnel barrier allows up to 100% spin-injection and detectio

Direct electronic measurement of Peltier cooling and heating in graphene
Autor: I. J. Vera-Marun, J. J. van den Berg, F. K. Dejene, B. J. van Wees
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-6 (2016)
The interaction of electric and thermal transport phenomena at the nanoscale leads to Seebeck and Peltier thermoelectric effects. Here, the authors directly detect the Peltier effect in graphene, and show that it can be reversed by controlling the ty

Electrically induced strong modulation of magnon transport in ultrathin magnetic insulator films
Autor: J. Liu, J. Ben Youssef, X. Y. Wei, B. J. van Wees, Gerrit E. W. Bauer
Publikováno v: Physical Review B, 103(21):214425. AMER PHYSICAL SOC
Magnon transport through a magnetic insulator can be controlled by current-biased heavy-metal gates that modulate the magnon conductivity via the magnon density. Here, we report nonlinear modulation effects in $10\phantom{\rule{0.16em}{0ex}}\mathrm{n

Magnetic order of Dy3+ and Fe3+ moments in antiferromagnetic DyFeO3 probed by spin Hall magnetoresistance and spin Seebeck effect
Autor: Maxim Mostovoy, Geert R. Hoogeboom, Gerrit E. W. Bauer, Alexey Kimel, Timo Kuschel, B. J. van Wees
Publikováno v: Physical Review B. 103
We report on spin Hall magnetoresistance (SMR) and spin Seebeck effect (SSE) in a single crystal of the rare-earth antiferromagnet DyFeO3 with a thin Pt film contact. The angular shape and symmetry of the SMR at elevated temperatures reflect the anti

Efficient Modulation of Magnon Conductivity in Y3Fe5O12 Using Anomalous Spin Hall Effect of a Permalloy Gate Electrode
Autor: J. Ben Youssef, O. Alves Santos, F. Feringa, K. S. Das, B. J. van Wees
Publikováno v: Physical Review Applied. 15
We report the control of the modulation efficiency of the magnon conductivity in yttrium iron garnet (YIG) using magnon spin injection from a ferromagnetic metal permalloy (Py) used as a modulator in a three-terminal magnon transistor geometry. The m
