Nonlocal Spin Transport as a Probe of Viscous Magnon Fluids
Camilo Ulloa, A. Tomadin, J. Shan +3
Magnons in ferromagnets behave as a viscous fluid over a length scale, the momentum-relaxation length, below which momentum-conserving scattering processes dominate. We show theore…
Gate-Controlled Magnetoresistance of a Paramagnetic Insulator|Platinum Interface
L. Liang, J. Shan, Q. H. Chen +6
We report an electric field-induced in-plane magnetoresistance of an atomically flat paramagnetic insulator|platinum (Pt) interface at low temperatures with an ionic liquid gate. T…
Enhanced magnon spin transport in NiFeO thin films on a lattice-matched substrate
J. Shan, A. V. Singh, L. Liang +4
We investigate magnon spin transport in epitaxial nickel ferrite (NiFeO, NFO) films grown on magnesium gallate spinel (MgGaO, MGO) substrates, which have a lattice…
Nonlocal magnon spin transport in yttrium iron garnet with tantalum and platinum spin injection/detection electrodes
Jing Liu, Ludo J. Cornelissen, Juan Shan +2
We study the magnon spin transport in the magnetic insulator yttrium iron garnet (YIG) in a nonlocal experiment and compare the magnon spin excitation and detection for the heavy m…
Magnon Planar Hall Effect and Anisotropic Magnetoresistance in a Magnetic Insulator
J. Liu, L. J. Cornelissen, J. Shan +2
Electrical resistivities can be different for charge currents travelling parallel or perpendicular to the magnetization in magnetically ordered conductors or semiconductors, result…
Influence of yttrium iron garnet thickness and heater opacity on the nonlocal transport of electrically and thermally excited magnons
Juan Shan, Ludo J. Cornelissen, Nynke Vlietstra +4
We studied the nonlocal transport behavior of both electrically and thermally excited magnons in yttrium iron garnet (YIG) as a function of its thickness. For electrically injected…
Temperature dependence of the magnon spin diffusion length and magnon spin conductivity in the magnetic insulator yttrium iron garnet
Ludo J. Cornelissen, Bart J. van Wees
We present a systematic study of the temperature dependence of diffusive magnon spin transport, using a non-local device geometry. In our measurements, we detect spin signals arisi…
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…
Simultaneous detection of the spin-Hall magnetoresistance and the spin-Seebeck effect in Platinum and Tantalum on Yttrium Iron Garnet
N. Vlietstra, M. Isasa, J. Shan +3
The spin-Seebeck effect (SSE) in platinum (Pt) and tantalum (Ta) on yttrium iron garnet (YIG) has been investigated by both externally heating the sample (using an on-chip Pt heate…
Exchange magnetic field torques in YIG/Pt bilayers observed by the spin-Hall magnetoresistance
N. Vlietstra, J. Shan, V. Castel +3
The effective field torque of an yttrium-iron-garnet film on the spin accumulation in an attached Pt film is measured by the spin-Hall magnetoresistance (SMR). As a result, the mag…
Spin-Hall Magnetoresistance in Platinum on Yttrium Iron Garnet: Dependence on platinum thickness and in-plane/out-of-plane magnetization
N. Vlietstra, J. Shan, V. Castel +2
The occurrence of Spin-Hall Magnetoresistance (SMR) in platinum (Pt) on top of yttrium iron garnet (YIG) has been investigated, for both in-plane and out-of-plane applied magnetic…
