Giant spin Nernst effect in a two-dimensional antiferromagnet due to magnetoelastic coupling-induced gaps and interband transitions between magnon-like bands
D. -Q. To, C. Y. Ameyaw, A. Suresh +7
We analyze theoretically the origin of the spin Nernst and thermal Hall effects in FePS3 as a realization of two-dimensional antiferromagnet (2D AFM). We find that a strong magneto…
Phonon-mediated strong coupling between a three-dimensional topological insulator and a two-dimensional antiferromagnetic material
D. Quang To, Weipeng Wu, Subhash Bhatt +8
Van der Waals antiferromagnetic and topological insulator materials provide powerful platforms for modern optical, electronic, and spintronic devices applications. The interaction…
Revealing room temperature ferromagnetism in exfoliated FeGeTe flakes with quantum magnetic imaging
Hang Chen, Shahidul Asif, Matthew Whalen +11
Van der Waals material FeGeTe, with its long-range ferromagnetic ordering near room temperature, has significant potential to become an enabling platform for implementing n…
Robustness of quantized transport through edge states of finite length: Imaging current density in Floquet topological vs. quantum spin and anomalous Hall insulators
Utkarsh Bajpai, Mark J. H. Ku, Branislav K. Nikolic
The theoretical analysis of topological insulators (TIs) has been traditionally focused on infinite homogeneous crystals with band gap in the bulk and nontrivial topology of their…
Imaging viscous flow of the Dirac fluid in graphene
Mark J. H. Ku, Tony X. Zhou, Qing Li +15
The electron-hole plasma in charge-neutral graphene is predicted to realize a quantum critical system whose transport features a universal hydrodynamic description, even at room te…
Spin-torque oscillation in a magnetic insulator probed by a single-spin sensor
H. Zhang, M. J. H. Ku, F. Casola +7
Coherent, self-sustained oscillation of magnetization in spin-torque oscillators (STOs) is a promising source for on-chip, nanoscale generation of microwave magnetic fields. Such f…
