The spin-1/2 Heisenberg ferromagnet on the pyrochlore lattice: A Green's function study

Condensed Matter Physics, 2018
We consider the pyrochlore-lattice quantum Heisenberg ferromagnet and discuss the properties of this spin model at arbitrary temperatures. To this end, we use the Green's function technique within the random-phase (or Tyablikov) approximation as well as ...

U-Pb dating of niobium minerals from the pyrochlore group (Ilmeny-Vishnevogorsky carbonatite-miaskite complex, South Urals)

Литосфера, 2020
The article covers the U-Pb dating of minerals belonging to the pyrochlore group from the rare-metal ore deposits of Ilmeny-Vishnevogorsky carbonatite-miaskite complex (South Urals). Individual pyrochlore crystals were dated through a new technique of in-

Weak magnetic transitions in pyrochlore Bi2Ir2O7

, 2013
Muon spin relaxation measurements on Bi2Ir2O7 show that it undergoes a bulk magnetic transition at 1.84(3) K. This is accompanied by increases in the muon spin relaxation rate and the amplitude of the non-relaxing part of the signal. The magnetic field experienced by muons is estimated to be 0.7 mT at low-temperature, around two orders of magnitude ...

Dry Reforming of Methane over Pyrochlore-Type La₂Ce₂O₇-Supported Ni Catalyst: Effect of Particle Size of Support

Molecules
The properties of supports (such as oxygen vacancies, oxygen species properties, etc.) significantly impact the anti-carbon ability due to their promotional effect on the activation of CO2 in dry reforming of methane (DRM).
