Advanced Science, Volume 13, Issue 2, 9 January 2026.Developing ultrathin wide‐temperature adaptive microwave absorption materials (MAMs) is crucial for enhancing the survival of military devices under alternating high‐temperature environment. Here, a double‐layer La2Zr2O7/Eu2Zr2O7 architecture is employed, with rare‐earth zirconates featuring with one‐eighth anion‐site vacancies, successfully achieving ...

Degenerate perturbation theory of quantum fluctuations in a pyrochlore antiferromagnet
, 2006 We study the effect of quantum fluctuations on the half-polarized magnetization plateau of a pyrochlore antiferromagnet. We argue that an expansion around the easy axis limit is appropriate for discussing the ground state selection amongst the ...

Quantum Spin Liquids Stabilized by Disorder in Non‐Kramers Pyrochlores
Annalen der Physik, Volume 538, Issue 1, January 2026.This study explores how random structural disorder induces a quantum spin‐liquid phase in non‐Kramers pyrochlore oxides. Using a real‐space gauge mean‐field approach to the random transverse‐field Ising model, we demonstrate that the quantum spin ice appears and remains remarkably robust against disorder, with only a narrow Griffiths region near the ...

Quantum spin ices and topological phases from dipolar-octupolar doublets on the pyrochlore lattice
, 2014 We consider a class of d- and f-electron systems in which dipolar-octupolar Kramers doublets arise on the sites of the pyrochlore lattice. For such doublets, two components of the pseudospin transform like a magnetic dipole, while the other transforms ...

Electric field response in breathing pyrochlores [PDF]
The European Physical Journal B, 2019 We study the effects of a uniform electric field on the the ground state and excitations of the three-dimensional U(1) spin liquid phase of a breathing pyrochlore lattice, arising due to the coupling between the conventional (Maxwell) electric field and the emergent electrodynamics of the quantum spin ice material.

Hydrothermal synthesis of perovskite and pyrochlore powders of potassium tantalate [PDF]
, 2002 Potassium tantalate powders were hydrothermally synthesized at 100 to 200 °C in 4 to 15 M aqueous KOH solutions. A defect pyrochlore, Kta_(2)O_(5)(OH). nH2O (n ≈ 1.4), was obtained at 4 M KOH, but at 7–12 M KOH, this pyrochlore was gradually replaced by ...

Pyrochlore Photons: The U(1) Spin Liquid in a S=1/2 Three-Dimensional Frustrated Magnet
, 2003 We study the S=1/2 Heisenberg antiferromagnet on the pyrochlore lattice in the limit of strong easy-axis exchange anisotropy. We find, using only standard techniques of degenerate perturbation theory, that the model has a U(1) gauge symmetry generated by
