Beyond Single‐Active Sites: The Emergence of High‐Entropy Perovskites in Energy and Environment Catalysis

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
This review examines high‐entropy perovskites (HEPs) as a promising catalyst platform for energy and environmental applications. The focus is on configurational entropy engineering, design and synthesis, and computational understanding. These materials possess tunable active sites, enhanced stability, and improved electronic interactions, leading to ...

Melting of spin ice state and development of fifth order susceptibility with magnetic field in pyrochlore Tb2Sn2O7

New Journal of Physics, 2022
Pyrochlores offer an ideal playground to investigate the magnetic ground state of frustrated magnetic systems. In this class of materials, competition between various magnetic interactions remains frustrated and prevents an ordered magnetic state at low ...

Insights on Lightning‐Induced Remanent Magnetization From High‐Current Impulse Experiments

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Lightning strikes generate intense transient magnetic fields capable of inducing strong and complex remanent magnetizations in rocks, potentially overprinting their original paleomagnetic record. To investigate the mechanisms and outcomes of lightning‐induced remanent magnetization, we conducted controlled high‐current impulse experiments on ...

Weyl magnons in breathing pyrochlore antiferromagnets [PDF]

Nature Communications, 2016
AbstractFrustrated quantum magnets not only provide exotic ground states and unusual magnetic structures, but also support unconventional excitations in many cases. Using a physically relevant spin model for a breathing pyrochlore lattice, we discuss the presence of topological linear band crossings of magnons in antiferromagnets.

Bionic Coulomb phase on the pyrochlore lattice [PDF]

Physical Review B, 2012
A class of three dimensional classical lattice systems with macroscopic ground state degeneracies, most famously the spin ice system, are known to exhibit "Coulomb" phases wherein long wavelength correlations within the ground state manifold are described by an emergent Maxwell electrodynamics. We discuss a new example of this phenomenon-the four state

NEXAFS and XPS Studies of Co Doped Bismuth Magnesium Tantalate Pyrochlores

Chemistry
Co doped bismuth magnesium tantalate with a pyrochlore structure (sp. gr. Fd-3m) was synthesized for the first time using the standard ceramic method. Single phase Bi2Mg1−xCoxTa2O9 samples were found to be formed when x < 0.7 in the X-ray phase analysis.

Topology‐Oriented Crystalline Architectures of Metal Oxides for Advanced Electrocatalytic Water Splitting

cScience, Volume 2, Issue 2, June 2026.
ABSTRACT Electrocatalytic water splitting remains a cornerstone strategy for sustainable hydrogen production; however, its overall efficiency is restricted by the sluggish oxygen evolution reaction. Metal oxides have emerged as highly promising catalysts owing to their adaptable electronic structures, high chemical stability, and abundant redox‐active ...

Effect of excess Mg and Excess Nb incorporation into the B-site of pyrochlore in the Pb-Mg-Nb-O system

Boletín de la Sociedad Española de Cerámica y Vidrio, 2002
In the Pb-Mg-Nb-O system, excess Mg and excess Nb incorporation into the B-site of PMN pyrochlore were investigated along the compositons of Pb1.83Mg0.29+xNb1.71-xO6.39-1.5x where x=0.1, 0.2, 0.3, 0.4, 0.522 and Pb1.83Mg0.29-xNb1.71+xO6.39+1.5x where x=0.

Inducing Ferromagnetism by Structural Engineering in a Strongly Spin‐Orbit Coupled Oxide

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
ABSTRACT Magnetic materials with strong spin‐orbit coupling (SOC) are essential for the advancement of spin‐orbitronic devices, as they enable efficient spin‐charge conversion, complex magnetic structures, spin‐valley physics, topological phases and other exotic phenomena.
