Pyrochlores belong to a numerous family of crystalline materials with a rich variety of
technologically important functional properties and developed structural diversity of possible …

Some inorganic solids undergo phase transitions that result in the formation of “molecules”
in their crystalline frameworks, which are frequently accompanied by dramatic changes in …

Transition-metal atoms with d electrons sometimes form clusters in crystals, which
significantly affect the physical properties. Such a cluster formation frequently accompanies …

The interplay of spin-orbit coupling with other relevant parameters gives rise to the rich
phase competition in complex ruthenates featuring octahedrally coordinated Ru4+. While …

Spin-orbit interaction has established itself as a key player in the emergent phenomena in
modern condensed matter, including topological insulator, spin liquid and spin-dependent …

The phenomenon of self-assembly of constituent elements to form molecules at low
temperatures appears ubiquitously in transition metal compounds with orbital degrees of …

We describe the existence of local distortion discovered in the synchrotron x-ray single-
crystal structure analysis of layered ditelluride 1 TM Te 2 (M= V, Nb, Ta). In 1 T-TaTe 2, the …

We report on the charge-ordered structure of Li Rh 2 O 4 arising below the metal-insulator
transition at 170 K. Structural studies using synchrotron x rays have revealed that the charge …

In this review, I present the electronic properties of the β-pyrochlore oxide CsW2O6 and
other related materials. At 215 K, CsW2O6 exhibits an electronic phase transition to a …

In systems with charge and orbital degrees of freedom, spontaneous molecular formation
phenomena occur at low temperatures as these degrees of freedom become entangled with …
