Ion-Assisted Nanoscale Material Engineering in Atomic Layers
Hossein Taghinejad, Mohammad Taghinejad, Sajjad Abdollahramezani +11
Achieving deterministic control over the properties of low-dimensional materials with nanoscale precision is a long-sought goal. Mastering this capability has a transformative impa…
Manipulating chiral-spin transport with ferroelectric polarization
Xiaoxi Huang, Xianzhe Chen, Yuhang Li +28
A collective excitation of the spin structure in a magnetic insulator can transmit spin-angular momentum with negligible dissipation. This quantum of a spin wave, introduced more t…
Tracking the evolution from isolated dimers to many-body entanglement in NaLuYbSe
Luke Pritchard Cairns, Ryan Day, Shannon Haley +5
We synthesize homogeneous compositions of NaLuYbSe, connecting non-magnetic NaLuSe to the triangular lattice spin liquid candidate NaYbSe. Thermal and magne…
Nonvolatile Electric Field Control of Thermal Magnons in the Absence of an Applied Magnetic Field
Eric Parsonnet, Lucas Caretta, Vikram Nagarajan +11
Spin transport through magnetic insulators has been demonstrated in a variety of materials and is an emerging pathway for next-generation spin-based computing. To modulate spin tra…
Electrically driven programmable phase-change meta-switch reaching 80% efficiency
Sajjad Abdollahramezani, Omid Hemmatyar, Mohammad Taghinejad +11
Despite recent advances in active metaoptics, wide dynamic range combined with high-speed reconfigurable solutions is still elusive. Phase-change materials (PCMs) offer a compellin…
