Pyrochlore-Supergroup Minerals Nomenclature: An Update [PDF]
Frontiers in Chemistry, 2021 The general formula of the pyrochlore-supergroup minerals is A2B2X6Y. The mineral names are composed of two prefixes and one root name (identical to the name of the group). The first prefix refers to the dominant anion (or cation or H2O or vacancy) of the dominant valence at the Y-site.

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.

Role of defects in determining the magnetic ground state of ytterbium titanate
Nature Communications, 2019 Exploring the role of structural defect is essential to understand the exotic quantum spin phenoma in rare earth pyrochlores. Here the authors show oxygen vacancies can stabilise the spin liquid phase and reveal the ferromagnetic ground state when oxygen

Manifestation of geometric frustration on magnetic and thermodynamic properties of pyrochlores $Sm_2X_2O_7$ (X=Ti, Zr) [PDF]
, 2007 We present here magnetization, specific heat and Raman studies on single-crystalline specimens of the first pyrochlore member $Sm_2Ti_2O_7$ of the rare-earth titanate series. Its analogous compound $Sm_2Zr_2O_7$ in the rare-earth zirconate series is also

Heat Capacity Measurements and Thermodynamic Assessment of the Y2O3–Ta2O5 System
Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.ABSTRACT Phase equilibria in the Y2O3–Ta2O5 system play an important role in the development of new materials for thermal barrier coating (TBC) applications, with higher thermal stability resulting in more efficient gas turbines with reduced exhaust gas emissions.

Cluster-glass phase in pyrochlore XY antiferromagnets with quenched disorder
, 2018 We study the impact of quenched disorder (random exchange couplings or site dilution) on easy-plane pyrochlore antiferromagnets. In the clean system, order-by-disorder selects a magnetically ordered state from a classically degenerate manifold.

Low-temperature muon spin rotation studies of the monopole charges and currents in Y doped Ho2Ti2O7 [PDF]
, 2013 In the ground state of Ho2Ti2O7 spin ice, the disorder of the magnetic moments follows the same rules as the proton disorder in water ice. Excitations take the form of magnetic monopoles that interact via a magnetic Coulomb interaction.
