Experimental demonstration of a robust training method for strongly defective neuromorphic hardware

December 11, 2023
Author(s)
William Borders, Advait Madhavan, Matthew Daniels, Vasileia Georgiou, Martin Lueker-Boden, Tiffany Santos, Patrick Braganca, Mark Stiles, Jabez J. McClelland, Brian Hoskins
Neural networks are increasing in scale and sophistication, catalyzing the need for efficient hardware. An inevitability when transferring neural networks to hardware is that non-idealities impact performance. Hardware-aware training, where non-idealities

Harmonic dependence of thermal magnetic particle imaging

September 22, 2023
Author(s)
Thinh Bui, Mark-Alexander Henn, Weston L. Tew, Megan Catterton, Solomon I. Woods
Advances in instrumentation and tracer materials are still required to enable sensitive and accurate 3D temperature monitoring by magnetic particle imaging. We have developed a magnetic particle imaging instrument to observe temperature variations using

Symmetry-dependent ultrafast manipulation of nanoscale magnetic domains

December 23, 2022
Author(s)
Nanna Hagstrom, Rahul Jangid, F. N. U. Meera, Diego Turenne, Jeffrey Brock, Erik Lamb, Boyan Stoychev, Justine Schlappa, Natalia Gerasimova, Benjamin Van Kuiken, Rafael Gort, Laurent Mercadier, Loic Le Guyader, Andrey Samartsev, Andreas Scherz, Giuseppe Mercurio, Hermann Durr, Alexander Reid, Monika Arora, Hans Nembach, Justin Shaw, Emmanuelle Jal, Eric Fullerton, Mark Keller, Roopali Kukreja, Stefano Bonetti, Thomas J. Silva, Ezio Iacocca
Symmetry is a powerful concept in physics, but its applicability to far-from-equilibrium states is still being understood. Recent attention has focused on how far-from-equilibrium states lead to spontaneous symmetry breaking. Conversely, ultrafast optical

Perpendicular magnetic tunnel junctions with multi-interface free layer

December 15, 2021
Author(s)
Pravin Khanal, Bowei Zhou, Magda Andrade, Yanliu Dang, Albert Davydov, Ali Habiboglu, Jonah Saidian, Adam Laurie, Jian-Ping Wang, Daniel Gopman, Weigang Wang
Future generations of magnetic random access memory demand magnetic tunnel junctions that can provide simultaneously high magnetoresistance, strong retention, low switching energy and small cell size below 10nm. Here we study perpendicular magnetic tunnel

The role of orientation in the MEL response of OLEDs

July 13, 2021
Author(s)
Sebastian Engmann, Emily Bittle, Lee J. Richter, Rawad Hallani, John Anthony, David J. Gundlach
Magneto electroluminescence (MEL) is emerging as a powerful tool for the study of spin dynamics in emitting devices. The shape of the MEL response is typically used to draw qualitative inference on the dominant process (singlet fission or triplet fusion)

Nonlinear losses in magnon transport due to four-magnon scattering

May 25, 2020
Author(s)
T. Hula, K. Schultheiss, A. Budzakov, L. Korber, M. Bejarano, L. Flacke, L. Liensberger, M. Weiler, Justin Shaw, Hans Nembach, J. Fassbender, H. Schultheiss
We report on the impact of nonlinear four-magnon scattering on magnon transport in microstructured Co 25Fe 75 waveguides with low magnetic damping. We determine the magnon propagation length with microfocused Brillouin light scattering over a broad range

Intrinsic spin currents in ferromagnets

June 24, 2019
Author(s)
Vivek P. Amin, Junwen Li, Mark D. Stiles, Paul M. Haney
First principles calculations show that electric fields applied to ferromagnets generate spin currents flowing perpendicularly to the electric field. Reduced symmetry in these ferromagnets enables a wide variety of such spin currents. However, the total

Electrical Detection of Singlet Fission in Single Crystal Tetracene Transistors

January 4, 2019
Author(s)
Hyuk-Jae Jang, Emily Bittle, Qin Zhang, Adam Biacchi, Curt A. Richter, David J. Gundlach
Here, we present the electrical detection of singlet fission in tetracene by using a field- effect transistor (FET). Singlet fission is a photo-induced spin-dependent process yielding two triplet excitons from the absorption of a single photon. , In this

Magnetotransport in highly enriched 28Si for quantum information processing devices

November 25, 2018
Author(s)
Aruna N. Ramanayaka, Ke Tang, Joseph Hagmann, Hyun S. Kim, Curt A. Richter, Joshua M. Pomeroy
Elimination of unpaired nuclear spins can result in low error rates for quantum computation; therefore, isotopically enriched 28Si is regarded as an ideal environment for quantum information processing devices. Using mass selected ion beam deposition
