Mechanochemical Nitrous Oxide Decomposition

open access: yesAdvanced Materials, EarlyView.
Nitrous oxide (N2O) is a potent greenhouse gas with a global warming potential of 310. A novel mechanochemical strategy is presented for decomposing N2O into harmless nitrogen and oxygen, achieving a rapid decomposition rate of 1761.3 mL h−1 and nearly complete N2O conversion of 99.98% at 42 °C.

Why T_c is too high when antiferromagnetism is underestimated? --- An understanding based on the phase string effect

open access: yes, 1999
It is natural for a Mott antiferromagnetism in RVB description to become a superconductor in doped metallic regime. But the issue of superconducting transition temperature is highly nontrivial, as the AF fluctuations in the form of RVB pair-breaking are ...

Interface‐Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room‐Temperature Hopfions and Skyrmions

open access: yesAdvanced Materials, EarlyView.
The first room‐temperature, zero‐field observation of stable skyrmion–hopfion spin textures in EuS─Bi2Se3─EuS trilayers is reported. Combining Lorentz TEM imaging and micromagnetic modeling, the authors unveil how interfacial Dzyaloshinskii–Moriya interaction and geometric confinement stabilize these multidimensional topological states.

Quantum Antiferromagnetism in Quasicrystals

open access: yes, 2002
The antiferromagnetic Heisenberg model is studied on a two-dimensional bipartite quasiperiodic lattice. The distribution of local staggered magnetic moments is determined on finite square approximants with up to 1393 sites, using the Stochastic Series ...

Transition of Néel‐Type and Bloch‐Néel Hybrid Skyrmion in a Metallic Multilayer Material System

open access: yesAdvanced Materials, EarlyView.
This work demonstrated a framework for manipulating multiple skyrmion types in [Pt/Co/Cu]5 multilayers through bias‐driven thermal effects. Distinct Néel and hybrid skyrmion phases can be selectively stabilized, enabling binary encoding beyond chirality‐based schemes.

Phil Anderson's Magnetic Ideas in Science [PDF]

open access: yes, 2016
In Philip W. Anderson's research, magnetism has always played a special role, providing a prism through which other more complex forms of collective behavior and broken symmetry could be examined. I discuss his work on magnetism from the 1950s, where his

Observation of ν = 5/2 Fractional Quantum Hall Effect in Trilayer Graphene Proximitized by V‐Doped WSe2

open access: yesAdvanced Materials, EarlyView.
Even‐denominator 5/2 fractional state in trilayer graphene/V‐doped WSe2 heterostructure, mediated by proximitized magnetism, is demonstrated. An exceptionally high energy gap ∆5/2 (48 K) for the 5/2 state, significantly surpassing previous values in semiconductors and bilayer graphene (∆5/2 < 1 K) is reported.
