Large Room Temperature Anomalous Nernst Effect Coupled with Topological Nernst Effect from Incommensurate Spin Structure in a Kagome Antiferromagnet

open access: yesAdvanced Science, EarlyView.
This study demonstrates that ErMn₆Sn₆, a kagome antiferromagnet hosting incommensurate spin textures, sustains finite scalar spin chirality that drives topological states. The anomalous Nernst effect (ANE) originates from the strong Berry curvature of Chern‐gapped Dirac fermions, while the topological Nernst effect (TNE) arises from emergent fields ...

Vortex states in superconductors with strong Pauli-paramagnetic effect

open access: yes, 2007
Using the quasiclassical theory, we analyze the vortex structure of strong-paramagnetic superconductors.There, induced paramagnetic moments are accumulated exclusively around the vortex core. We quantitatively evaluate the significant paramagnetic effect

Small-angle neutron scattering correlation functions of bulk magnetic materials

open access: yesJournal of Applied Crystallography, 2015
On the basis of the continuum theory of micromagnetics, the correlation function of the spin-misalignment small-angle neutron scattering cross section of bulk ferromagnets is computed and discussed.

Is There A Pure Electronic Ferroelectric?

open access: yesAdvanced Electronic Materials, EarlyView.
The search for faster, more reliable ferroelectric materials has shifted from traditional lattice‐driven ferroelectrics, which rely on slow ionic displacements, to electronic ferroelectrics, where polarization is governed by electronic ordering. This shift enables ultrafast switching, low‐field operation, and resistance to fatigue.

Synergetic Lattice and Surface Engineering: Stable High‐Voltage Cycle Performance in P3‐Type Layered Manganese Oxide

open access: yesAdvanced Energy Materials, EarlyView.
A dual lattice‐surface strategy employing NaTi2(PO4)3 is adopted to enhance the performance of P3‐type Na0.67[Zn0.3Mn0.7]O2, whereby Ti stabilizes the bulk lattice and surface P species mitigate degradation, collectively improving high‐voltage cycling stability, Na+ diffusion, and oxygen redox reversibility through synergistic structural and ...

Decoding Short‐Range Order in Amorphous Two‐Dimensional Nanosheets for Efficient and Durable Ampere‐Level Seawater Electrolysis: A Case Study of Amorphous Ni(OH)2

open access: yesAdvanced Energy Materials, EarlyView.
This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances

Element Specific Room Temperature Non‐Collinear Magnetism in the M‐Type Hexaferrite SrCo1.2Ti1.2Fe9.6O19${\rm SrCo}_{1.2}{\rm Ti}_{1.2}{\rm Fe}_{9.6}{\rm O}_{19}$

open access: yesAdvanced Physics Research, EarlyView.
Non‐collinear magnetism is of high interest in the field of magnetoelectrics supplying a convenient mechanism to break inversion symmetry and thereby allowing for a spontaneous electrical polarization. Such “multiferroics of spin origin” are inherently suitable for electric field control of magnetism, offering a route toward low power ICT applications.
