Features of Synthesis, Crystal Structure, Thermal and Electrical Properties, XPS/NEXAFS Study of Pyrochlore-Type Bi₂Cr_0.5Co_0.5Nb₂O_9+Δ

Chemistry
The phase-pure cubic pyrochlore of the Bi2Cr0.5Co0.5Nb2O9+Δ composition can be successfully synthesized by a modified sol–gel method (Pecini method-PM) and a traditional solid-phase method (SPM).

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 ...

Depleted pyrochlore antiferromagnets

Journal of Physics: Conference Series, 2009
I consider the class of "depleted pyrochlore" lattices of corner-sharing triangles, made by removing spins from a pyrochlore lattice such that every tetrahedron loses exactly one. Previously known examples are the "hyperkagome" and "kagome staircase".

Tuning properties through disorder: structural, optical, and mechanical insights into novel medium-entropy rare-earth hafnate pyrochlores

Materials Research Express
Entropy-stabilized oxides find application in several areas due to their interesting properties which comes from the four core attributes—entropy-stabilization effect, severe lattice distortion effect, sluggish diffusion effect and cocktail effect.
