Confinement of rotating convection by a laterally varying magnetic field

open access: yes, 2017
Spherical shell dynamo models based on rotating convection show that the flow within the tangent cylinder is dominated by an off-axis plume that extends from the inner core boundary to high latitudes and drifts westward.

Coexisting Rashba/Dresselhaus Spin Splitting in Solution‐Processed Bournonite Films Using Circular Photogalvanic Effect

open access: yesAdvanced Functional Materials, EarlyView.
Circular photogalvanic effect measurements and first‐principles calculations reveal spin‐splitting states in solution‐processed bournonite films (CuPbSbS3) due to structural and bulk inversion asymmetry. The results provide experimental confirmation of coexisting Rashba and Dresselhaus spin‐splitting states in this non‐centrosymmetric chalcogenide ...

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

Observation of Relativistic Domain Wall Motion in Amorphous Ferrimagnets

open access: yesAdvanced Functional Materials, EarlyView.
Domain walls in ferrimagnets and antiferromagnets move as relativistic sine‐Gordon solitons, with the spin‐wave velocity setting their speed limit. Such relativistic domain‐wall motion is demonstrated in amorphous GdFeCo near angular momentum compensation, where current‐driven walls reach 90% of the 2 kms−1 spin‐wave speed, enabling ultrafast, device ...

Universal Electronic‐Structure Relationship Governing Intrinsic Magnetic Properties in Permanent Magnets

open access: yesAdvanced Functional Materials, EarlyView.
Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...

On the Earth’s magnetic field and the Hall effect [PDF]

open access: yesNonlinear Processes in Geophysics, 2003
In a recent paper de Paor put forward a new theory of the Earth's magnetic field that depended on the Hall effect as an energy transfer mechanism. The purpose of this paper is to demonstrate that the mechanism invoked is unimportant except in certain

Metallofullerenol Sc3N@C80(OH)18: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short‐ and Long‐Lived Radicals

open access: yesAdvanced Healthcare Materials, EarlyView.
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

North-south asymmetry of geomagnetic activity and solar wind electric

open access: yesSolar-Terrestrial Physics, 2016
Geomagnetic activity asymmetry in the Northern and Southern hemispheres is studied. It is shown that the higher is the level of magnetic activity the greater is the asymmetry.
