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 …

The sustainable development of civil nuclear energy requires the fabrication of the durable
nuclear wasteforms, in particular for high-level radioactive waste, which involves the design …

We report dramatically different behaviors between isostructural Gd 2 Ti 2 O 7 and Gd 2 Zr 2
O 7 pyrochlore at pressures up to 44 GPa, in which the substitution of Ti for Zr significantly …

The pyrochlore oxides (A 2 B 2 O 7) exhibit a remarkable range of structural, physical, and
magnetic properties related to their various chemical compositions. This article reports the …

Pyrochlore compositions in the Gd2 (Ti1− xZrx) 2O7 solid solution have gained attention in
the field of radioactive waste forms because they are capable of withstanding high doses of …

The phonon and crystal field excitations in several rare earth titanate pyrochlores are
investigated. Magnetic measurements on single crystals of Gd 2 Ti 2 O 7, Tb 2 Ti 2 O 7, Dy 2 …

A temperature-dependent Raman study of Ho 2 Ti 2 O 7 and Dy 2 Ti 2 O 7 single crystals
was performed in the 5–873 K temperature range. Polarized spectra allowed us to establish …

The temperature‐dependent Raman studies of A2Ti2O7 (A= Dy, Er, Gd) were performed on
single crystals and polycrystalline samples in the 4.2–295 K temperature range. The Raman …

We present here magnetization, specific heat, and Raman studies on single-crystalline
specimens of the first pyrochlore member Sm 2 Ti 2 O 7 of the rare-earth titanate series. Its …

Complex oxides with the pyrochlore (A 2 B 2 O 7) and defect-fluorite ((A, B) 4 O 7) structure-
types undergo structural transformations under high-pressure. Rare-earth hafnates (A 2 Hf 2 …
