Visualization of Single Spin-chain Propagation using Bragg Coherent Diffraction Imaging
Xiaoqian M. Chen, Justin S. Woods, Ulrich Welp +11
Domain wall dynamics and their manipulation in finite-size systems serve as a promising platform for beyond Moore's law applications. Yet, the imaging techniques to track their mot…
X-ray Fractional Orbital Angular Momentum from Coherent Magnetic Scattering
P. D. Montgomery, J. S. Woods, M. R. McCarter +10
Artificial spin ice (ASI) based on a square lattice with a topological defect are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigati…
A Low-Dissipation and Scalable GEMM Accelerator with Silicon Nitride Photonics
Venkata Sai Praneeth Karempudi, Sairam Sri Vatsavai, Ishan Thakkar +3
Over the past few years, several microring resonator (MRR)-based analog photonic architectures have been proposed to accelerate general matrix-matrix multiplications (GEMMs), which…
Spontaneous Magnetic Superdomain Wall Fluctuations in an Artificial Antiferromagnet
X. M. Chen, B. Farmer, J. S. Woods +8
Collective dynamics often play an important role in determining the stability of ground states for both naturally occurring materials and metamaterials. We studied the temperature…
Direct Imaging of Complex Spin Ice Behavior and Ordered Sublattices in Artificial Ferromagnetic Quasicrystals
V. S. Bhat, A. Balk, B. Farmer +5
We have imaged magnetization textures of permalloy films patterned into Penrose P2 tilings (P2T) using scanning electron microscopy with polarization analysis (SEMPA). P2T film seg…
