Flux Jamming and Bimodal Dynamics in Bounded Spin Networks
Paula Mellado, Hanu Arava
We present a quantitative framework for predicting how kinetic barriers governing temperature dependent relaxation arise in finite square magnetic networks. By formulating a series…
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…
Synthesis and transport properties of epitaxial Bi (111) films on GaAs (111) substrates
Jagannath Jena, Eugene D. Ark, Siddhesh Ambhire +12
In recent decades, the growth of ultrathin epitaxial bismuth (Bi) films on various substrates has garnered interest due to their unique electronic properties. We report upon the gr…
A15 Phase Ta3Sb Thin Films: Direct Synthesis, Charge Transport and Spin-Orbit Torque
J. S. Jiang, Qianheng Du, Yi Li +9
Ta3Sb is one of the A15 compounds that have been predicted to have giant spin Hall conductivities due to the gapped Dirac-like band crossings in their electronic structures. We use…
Automated Imaging of the Annihilation of a Transverse Domain Wall in Patterned Magnetic Thin Films
Charudatta Phatak, John Fullerton, Hanu Arava
Imaging the magnetic domain wall behavior in patterned thin films under external stimuli can enable understanding the underlying energy landscape as well as the role of local micro…
