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…
Long distance transport of magnon spin information in a magnetic insulator at room temperature
L. J. Cornelissen, J. Liu, R. A. Duine +2
The transport of spin information has been studied in various materials, such as metals, semiconductors and graphene. In these materials, spin is transported by diffusion of conduc…
Gate-Voltage Control of Chemical Potential and Weak Anti-localization in Bismuth Selenide
J. Chen, H. J. Qin, F. Yang +10
We report that BiSe thin films can be epitaxially grown on SrTiO substrates, which allow for very large tunablity in carrier density with a back-gate. The observed lo…
Suppressed spin dephasing for 2D and bulk electrons in GaAs wires due to engineered cancellation of spin-orbit interaction terms
S. Z. Denega, T. Last, J. Liu +7
We report a study of suppressed spin dephasing for quasi-one-dimensional electron ensembles in wires etched into a GaAs/AlGaAs heterojunction system. Time-resolved Kerr-rotation me…
Spin-dephasing anisotropy for electrons in a diffusive quasi-1D GaAs wire
J. Liu, T. Last, E. J. Koop +3
We present a numerical study of dephasing of electron spin ensembles in a diffusive quasi-one-dimensional GaAs wire due to the D'yakonov-Perel' spin-dephasing mechanism. For widths…
The influence of device geometry on many-body effects in quantum point contacts: Signatures of the 0.7 anomaly, exchange and Kondo
E. J. Koop, A. I. Lerescu, J. Liu +4
The conductance of a quantum point contact (QPC) shows several features that result from many-body electron interactions. The spin degeneracy in zero magnetic field appears to be s…
