Confirming the origin of Gilbert damping by experiment has remained a challenge for many decades, even simple ferromagnetic metals. Here, we experimentally identify that increases with decreasing electronic scattering in epitaxial thin films pure Fe. This observation conductivitylike damping, which cannot be accounted classical eddy-current loss, is excellent quantitative agreement theoretical predictions due to intraband scattering.

It is important to develop a catalyst that has high catalytic activity and can improve the degradation efficiency of refractory organic pollutants in ozonation process. In this study, Fe-Mn-Cu-Ce/Al2O3 was synthesised via impregnation calcination for bio-treated coking wastewater.

To develop low-moment, low-damping metallic ferromagnets for power-efficient spintronic devices, it is crucial to understand how magnetic relaxation impacted by the addition of nonmagnetic elements. Here, we compare in epitaxial Fe films alloyed with light elements V and Al. FeV alloys exhibit lower intrinsic damping compared pure Fe, reduced nearly a factor 2, whereas FeAl increases Al content. Our experimental computational results indicate that reducing density states at Fermi level,...

How spin-orbit torques emerge from materials with weak coupling (e.g., light metals) is an open question in spintronics. Here, we report on a field-like torque (i.e., in-plane field transverse to the current axis) SiO$_2$-sandwiched permalloy (Py), top Py-SiO$_2$ interface incorporating ultrathin Ti or Cu. In both SiO$_2$/Py/Ti/SiO$_2$ and SiO$_2$/Py/Cu/SiO$_2$, this opposes classical Oersted field. While magnitude of at least factor 3 greater than field, do not observe evidence for...

Artificial neural networks can achieve impressive performances, and even outperform humans in some specific tasks. Nevertheless, unlike biological brains, the artificial suffer from tiny perturbations sensory input, under various kinds of adversarial attacks. It is therefore necessary to study origin vulnerability. Here, we establish a fundamental relationship between geometry hidden representations (manifold perspective) generalization capability deep networks. For this purpose, choose...

Developers change software programs for various purposes (e.g., bug fixes, feature additions, and code refactorings), but the intents of changes are often not recorded or poorly documented. To automatically infer intent each program commit (i.e., a set changes), existing work classifies commits based on messages and/or sheer counts edited files, lines, abstract syntax tree (AST) nodes. However, none these tools reason about syntactic semantic dependencies between co-applied changes, neither...
