Pyrochlore (Na, Ca)2 Nb 2 O 6(OH, F) is a mineral group of the niobium end member of the pyrochlore supergroup. Pyrochlore is also a term for the crystal structure F d 3 m.

Nov 11, 2021 · In this article we provide some perspectives on a range of pyrochlore and defect fluorite type compounds with nominal A 2 B 2 O 7, A 2 BO 5, ABC 2 O 7, and other stoichiometries.

Compositions, cubic unit cell parameters (a, space group Fd3 ̄m, #227), and structural formulas for single-phase pyrochlore specimens. These compositions correspond to the points within the four-sided pyrochlore region shown in Figure 4.

Jun 25, 2021 · Owing to comparably strong spin-orbit coupling and Hubbard interaction, iridium based 227 pyrochlore oxides harbor a rich confluence of competing magnetic orders and emergent multipolar Weyl quasiparticles.

Aug 10, 2017 · In this paper, we report on systematic measurements of the structural, compositional, and electrical transport properties of a prototypical pyrochlore iridate, namely Bi-227 thin films.

Oct 1, 2024 · These compounds crystallize in the Fd ̄3m cubic structure (space group No. 227) consisting of two interpenetrating rare-earth and iridium pyrochlore sublattices (Fig. 1) that are connected via a d- f interaction, making them a fertile playground to discover phases and to study frustrated magnetism [1,2,5,11].

Jul 25, 2012 · We present results from muon spin relaxation/rotation, magnetization, neutron scattering, and transport measurements on polycrystalline samples of the pyrochlore iridates Y Ir O (Y-227) and Yb Ir O (Yb-227).

Owing to comparably strong spin-orbit coupling and Hubbard interaction, iridium based 227 pyrochlore oxides harbor a rich confluence of competing magnetic orders and emergent multipolar Weyl...

Mar 29, 2012 · We present results from muon spin relaxation/rotation, magnetization, neutron scattering and transport measurements on polycrystalline samples of the pyrochlore iridates Y2Ir2O7 (Y-227) and Yb2Ir2O7 (Yb-227).

For the trivalent lanthanons from La to Lu, and for Y, the ho~nogeneousA2Sn207 phases were of the cubic pyrochlore type (space group FdSm, No. 227). Their lattice parameters gave a very good linear relationship when plotted against the Templeton-Dauben radii of A3+.
