A voltage-responsive strongly dipolar-coupled macrospin network with emergent dynamics for computing
Xinglong Ye, Zhibo Zhao, Qian Wang +15
Emergent behavior, which arises from local interactions between simple elements, is pervasive in nature. It underlies the energy-efficient computing in our brains. However, realizi…
Plasma engineered Hydroxyl Defects in NiO a DFTSupported-Spectroscopic Analysis of Oxygen Hole States and Implications for Water Oxidation
Harol Moreno Fernandez, Mohammad Amirabbasi, Crizaldo Jr. Mempin +8
Controlling lattice oxygen reactivity in earth abundant OER catalysts requires precise tuning of defect chemistry in the oxide lattice. Here, we combine DFT+U calculations with pla…
Two-component anomalous Hall and Nernst effects in anisotropic FeGeN thin films
R. K. Paul, J. VÃt, P. Levinský +18
A series of thin films FeGeN (x=0-1) was fabricated onto MgO substrates by magnetron sputtering with the aim of studying the possible enhancement of the anomalous Nerns…
Coercivity influence of nanostructure in SmCo-1:7 magnets: Machine learning of high-throughput micromagnetic data
Yangyiwei Yang, Patrick Kühn, Mozhdeh Fathidoost +9
As a pinning-controlled permanent magnet, tailoring the cellular nanostructure of samarium-cobalt-based 1:7-type (SmCo-1:7) magnets remains crucial for improving magnetic performan…
Direct observation of nanoscale pinning centers in Ce(Co0.8Cu0.2)5.4 permanent magnets
Nikita Polin, Shangbin Shen, Fernando Maccari +15
Permanent magnets containing rare earth elements are essential components for the electrification of society. Ce(Co1-xCux)5 permanent magnets are a model system known for their sub…
DFT-Guided Operando Raman Characterization of Ni-Based Phases Relevant to Electrochemical Systems
Harol Moreno Fernández, Siavash Karbasizadeh, Esmaeil Adabifiroozjaei +3
We present a phase-resolved investigation of Ni-based oxides and hydroxides relevant to the oxygen evolution reaction (OER), combining ground-state DFT+U calculations with operando…
