Anisotropic Charge Diffusion in Polar‐Layered Oxides for Ultralong Charge Retention

open access: yesAdvanced Science, EarlyView.
Anisotropic charge diffusion in epitaxially grown LAO thin films is reported, which enables ultralong charge retention. Surface‐accumulated oxygen vacancies effectively suppress out‐of‐plane electron hopping, allowing ≈90.9% of the surface charges to remain after a few weeks or longer.

Paradoxical Topological Soliton Lattice in Anisotropic Frustrated Chiral Magnets

open access: yesAdvanced Science, EarlyView.
The article describes the discovery of a stable skyrmion‐antiskyrmion lattice (S‐AL) in anisotropic frustrated chiral magnets. This lattice has a net‐zero topological charge due to a balanced population of skyrmions and antiskyrmions. This is a paradoxical finding since these particles normally annihilate each other.

Mechanism of Anomalous Anisotropic Colossal Magnetoresistance in Quasi‐2D Mn3Si2Te6 Bulk Single Crystal

open access: yesAdvanced Science, EarlyView.
The external field exceeds Hd, the speed polarization abruptly reorients to align with the Mn magnetic moments, leading to an MR ≈ −100%. Abstract Mn3Si2Te6, quasi‐2D ferrimagnetic semiconductor, exhibits anomalous saturated colossal magnetoresistance (CMR) only when a magnetic field is applied along its magnetic hard magnetization axis, suggesting ...

Two‐Dimensional Alloying at the Iron‐Copper Interface in Steel Driven by Magnetic Friedel Oscillations

open access: yesAdvanced Science, EarlyView.
The interlayer magnetic couplings (left) and the changes of atomic‐layer‐averaged electron density (right) for Fe and Cu sides near the sharp and diffuse Fe/Cu (001) interfaces reveal that magnetic Friedel oscillations at Fe/Cu interfaces in steel drive atomic‐scale 2D alloying, resolving the long‐standing paradox of high Fe content in Cu precipitates.
