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…
Physics-Informed Deep Image Prior Reconstruction of In-Plane Magnetization from Scanning NV Magnetometry
Zander Scholl, Justin Woods, Charudatta Phatak +1
Reconstructing magnetization in nanoscale magnetic thin films is essential for developing next-generation memory, sensors, and various spintronic technologies. However, this remain…
Antiferromagnetic real-space configuration probed by dichroism in scattered x-ray beams with orbital angular momentum
Margaret R. McCarter, Ahmad I. U. Saleheen, Arnab Singh +8
X-ray beams with orbital angular momentum (OAM) are a promising tool for x-ray characterization techniques. Beams with OAM have a helicity--an azimuthally varying phase--which lead…
Angular-Dependent Dynamic Response and Magnetization Reversal in Fibonacci-Distorted, Kagome Artificial Spin Ice
Ali Frotanpour, Justin Woods, Barry Farmer +2
We have measured the angular dependence of ferromagnetic resonance (FMR) spectra for Fibonacci-distorted, Kagome artificial spin ice (ASI). The number of strong modes in the FMR sp…
Magnetization Dynamics of Fibonacci-Distorted Kagome Artificial Spin Ice
Ali Frotanpour, Justin Woods, Barry Farmer +4
We present results of ferromagnetic resonance (FMR) experiments and micromagnetic simulations for a distorted, 2D Kagome artificial spin ice. The distorted structure is created by…
Switchable X-ray Orbital Angular Momentum from an Artificial Spin Ice
Justin Woods, Xiaoqian M Chen, Rajesh V. Chopdekar +12
Artificial spin ices (ASI) have been widely investigated as magnetic metamaterials with exotic properties governed by their geometries. In parallel, interest in X-ray photon orbita…
Vertex Dependent Dynamic Response of a Connected Kagome Artificial Spin Ice
Ali Frotanpour, Justin Woods, Barry Farmer +2
We present the dynamic response of a connected Kagome artificial spin ice with emphasis on the effect of the vertex magnetization configuration on the mode characteristics. We use…
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…
