The structural phase transition in SrV6O11

Structural phase transition in epitaxial perovskite films

Three different film systems have been systematically investigated to understand the effects of strain and substrate constraint on the phase transitions of perovskite films. In SrTiO3 films, the phase transition temperature Tc was determined by monitoring the superlattice peaks associated with rotations of TiO6 octahedra. It is found that Tc depends on both SrTiO3 film thickness and SrRuO3 buff...

Structural Phase Transition Accompanied by Metal - Insulator Transition in PrRu4P12

A structural phase transition has been found using electron diffraction technique in PrRu4P12 accompanied by a metal insulator (M I) transition (TMI = 60K). Weak superlattice spots appeared at (H, K, L) (H + K + L = 2n + 1; n is an integer) position at a temperature of T = 12 K and 40 K. Above T = 70 K, the spots completely vanished. The space group of the low temperature phase is probably Pm 3...

Dynamics of the magneto structural phase transition in

The structural phase transition in SrV(6)O(11).

Single-crystal X-ray diffraction and specific heat studies establish that strontium hexavanadium undecaoxide, SrV(6)O(11), undergoes a P6(3)/mmc to inversion twinned P6(3)mc structural transition as the temperature is lowered through 322 K. The P6(3)/mmc and P6(3)mc structures have been determined at 353 K and at room temperature, respectively. For the room-temperature structure, seven of the t...
