Within the past 20 years or so, there has occurred an explosion of interest in the magnetic
behavior of pyrochlore oxides of the type A 2 3+ B 2 4+ O 7, where A is a rare-earth ion and …

In this article we provide some perspectives on a range of pyrochlore and defect fluorite type
compounds with nominal A2B2O7, A2BO5, ABC2O7, and other stoichiometries. Typically …

Structural and functional applications involving La 2 Zr 2 O 7 exploit the data on fluorite to
pyrochlore phase transition, because of the strong dependence on the physical properties of …

The class of oxygen-ion-conducting rare-earth pyrochlores has been considerably
extended. New solid electrolytes, Ln 2 Ti 2 O 7 (Ln= Dy-Lu) and Ln 2 Hf 2 O 7 (Ln= Eu, Gd) …

Three-dimensionally (3D) frustrated magnets generally exist in the magnetic diamond and
pyrochlore lattices, in which quantum fluctuations suppress magnetic orders and generate …

The spin-glass behavior of Y 2 Mo 2 O 7 has remained a puzzle for nearly three decades.
Free of bulk disorder within the resolution of powder diffraction methods, it is thought that this …

Pyrochlore systems are ideally suited to the exploration of geometrical frustration in three
dimensions, and their rich phenomenology encompasses topological order and fractional …

The long-range average and short-range local structures in the Tm2 (Ti2–x Tm x) O7–x/2 (x=
0.00–0.67) series were studied using a combination of diffraction and spectroscopic …

Pyrochlores based on the general composition Ln2TiO5 (Ln2. 67Ti1. 33O6. 67) and
Ln2Ti2O7, where Ln= Y or Yb, have been irradiated through the crystalline–amorphous …

During recent years the interest to frustrated magnets has grown considerably. Such
systems reveal very peculiar properties which distinguish them from standard paramagnets …
