Journal ArticleDOI
Controlled Magnetic Reversal in Permalloy Films Patterned into Artificial Quasicrystals
V. S. Bhat,Joseph Sklenar,Barry Farmer,Justin Woods,Jeffrey Todd Hastings,S. J. Lee,John B Ketterson,L. E. De Long +7 more
TL;DR: Micromagnetic simulations compare well to experimental dc hysteresis loops and ferromagnetic resonance spectra and indicate that systematic control of magnetic reversal and domain wall motion can be achieved via tiling design, offering a new paradigm of magnonic quasicrystals.
Journal ArticleDOI
Magnetic response of aperiodic wire networks based on Fibonacci distortions of square antidot lattices
Barry Farmer,V. S. Bhat,Joseph Sklenar,E. Teipel,Justin Woods,John B Ketterson,Jeffrey Todd Hastings,L. E. De Long +7 more
TL;DR: In this article, a permalloy wire network based on periodic square antidot lattices (ADLs) distorted according to an aperiodic Fibonacci sequence applied to two lattice translations was fabricated.
Journal ArticleDOI
Spontaneous Magnetic Superdomain Wall Fluctuations in an Artificial Antiferromagnet.
Xiaoqian Chen,Xiaoqian Chen,Barry Farmer,Justin Woods,Justin Woods,Scott Dhuey,Wen Hu,Claudio Mazzoli,Stuart Wilkins,Rajesh V. Chopdekar,Andreas Scholl,Ian K. Robinson,Ian K. Robinson,L. E. De Long,Sashwati Roy,Jeffrey Todd Hastings +15 more
TL;DR: This work studied the temperature dependent dynamics of antiferromagnetically ordered superdomains in a square artificial spin lattice using soft x-ray photon correlation spectroscopy and observed an exponential slowing down of superdomain wall motion below the antiferromeagnetic onset temperature.
Journal ArticleDOI
Ferromagnetic resonance study of eightfold artificial ferromagnetic quasicrystals
V. S. Bhat,Joseph Sklenar,Barry Farmer,Justin Woods,John B Ketterson,Jeffrey Todd Hastings,L. E. De Long +6 more
TL;DR: In this paper, the authors performed broadband and narrowband FMR measurements on permalloy thin films patterned with quasiperiodic Ammann tilings having eightfold rotational symmetry.
Journal ArticleDOI
Switchable X-ray Orbital Angular Momentum from an Artificial Spin Ice
Justin Woods,Justin Woods,Xiaoqian Chen,Xiaoqian Chen,Rajesh V. Chopdekar,Barry Farmer,Claudio Mazzoli,Roland J. Koch,Anton S. Tremsin,Wen Hu,Andreas Scholl,Stephen D. Kevan,Stuart Wilkins,Wai-Kwong Kwok,Lance E. De Long,Sujoy Roy,J. Todd Hastings +16 more
TL;DR: It is shown that a square ASI with a patterned topological defect, a double edge dislocation, imparts OAM to scattered x rays, demonstrating ASIs can serve as metasurfaces for reconfigurable x-ray optics that could enable selective probes of electronic and magnetic properties.
