THE PYROCHLORE SUPERGROUP OF MINERALS: NOMENCLATURE
(MINERALOGICAL ASSOC CANADA, 2010)
A new scheme of nomenclature for the pyrochlore supergroup, approved by the CNMNC-IMA, is based on the ions at the A, B and Y sites. What has been referred to until now as the pyrochlore group should be referred to as the ...
Monte Carlo study on the detection of classical order by disorder in real antiferromagnetic Ising pyrochlores
(American Physical Society, 2019-11-04)
We use Monte Carlo simulations to evaluate the feasibility of detecting thermal order by disorder in real antiferromagnetic Ising pyrochlores, frustrated by a magnetic field applied in the [110] direction. Building on an ...
A comprehensive examination of the local- and long-range structure of Sb6O13 pyrochlore oxide
(Nature Research, 2020-12)
The crystal structure of the Sb6O13 oxide, exhibiting a defect pyrochlore crystal structure with atomic vacancies, has been studied using a complete set of state-of-the-art techniques. The degree of antimony disproportionation ...
Potassium disorder in the defect pyrochlore KSbTeO6: A neutron diffraction study
(MDPI AG, 2017-01-13)
KSbTeO6 defect pyrochlore has been prepared from K2C2O4, Sb2O3, and 15% excess TeO2 by solid-state reaction at 850 °C. Direct methods implemented in the software EXPO2013 allowed establishing the basic structural framework. ...
Preparation of pyrochlore-free PMN by an alternative chemical method
(Taylor & Francis Ltd, 2006-01-01)
This work reports the synthesis of the MgNb(2)O(6) and the ferroelectric lead magnesium niobate Pb(Mg(1/3)Nb(2/3))O(3) (PMN) using fine precursor powders obtained from a chemical Oxide Precursor Method (OPM). To obtain ...

Phase analysis of seeded and doped PbMg1/3Nb2/3O3 prepared by organic solution of citrates
(1996-07-01)
PbMg1/3Nb2/3O3 (PMN) prepared by organic solution of citrates was analyzed by the Rietveld method to determine the influence of seeds and dopants on the perovskite and pyrochlore phase formation. It was observed that ...
