Field-driven triggering of self-induced Floquet magnons in a magnetic vortex
R. Lopes Seeger, G. Philippe, A. Jenkins +5
We report the experimental control of Floquet magnons in a magnetic vortex. Using microwave spectroscopy of vortex state magnetic tunnel junctions (MTJs), we find that self-induced…
Non-Volatile Vortex MTJs with Opto-Electrical and Spin-Diode Nonlinearities as Multifunctional Neuromorphic Platforms
Felix Oberbauer, Tristan Joachim Winkel, Clara C Wanjura +6
The human brain achieves exceptional energy efficiency by co-locating memory and processing, yet reproducing this principle in hardware remains challenging because many neuromorphi…
Hybrid Opto-Electrical Excitation of Spin-Transfer Torque Nano-Oscillators for Advanced Computing
Felix Oberbauer, Tristan Joachim Winkel, Tim Böhnert +8
Neuromorphic computing, inspired by the brain's parallel and energy-efficient processing, offers a transformative approach to artificial intelligence. In this study, we fabricated…
Reconfigurable classifier based on spin torque driven magnetization switching in electrically connected magnetic tunnel junctions
A. Lopez, D. Costa, T. Bohnert +7
A promising branch of neuromorphic computing aims to perform cognitive operations in hardware leveraging the physics of efficient and well-established nano-devices. In this work, w…
