HIGH-PRESSURE CRYSTAL CHEMISTRY AND AMORPHIZATION OF e-QUARTZ
Single-crystal X-ray diffraction experiments on e-quartz at pressures to 15 GPa reveal structural instabilities that result in its gradual transition to an amorphous state. With increasing pressure the average Si-O distance ( ~ 1.61 + 0.01/~) and S i O 4 tetrahedral volume (,,~2.14 ___ 0.02.~ 3) remain constant. Compression of e-quartz results from a dramatic decrease in Si-O-Si angle and corre...
متن کاملSpin transition induced by crystal – liquid crystal transition
Cobalt(II) compounds [Co(C10C8C2-terpy)2](BF4)2 (1) and [Co(C12C10C2terpy)2](BF4)2 (2) (CxCyCz-terpy = 4’-5’’’-Alkyl-1’’’-alkoxy-2,2’:6’,2’’-terpyridine) with branched alkyl chains, based on a terpyridine frame, were synthesized. The cobalt(II) compounds 1 and 2 exhibit the spin transition between low-spin and high-spin with thermal hysteresis loop at the liquid crystal transition temperature (...
متن کاملDepressurization amorphization of single-crystal boron carbide.
We report depressurization amorphization of single-crystal boron carbide (B4C) investigated by in situ high-pressure Raman spectroscopy. It was found that localized amorphization of B4C takes place during unloading from high pressures, and nonhydrostatic stresses play a critical role in the high-pressure phase transition. First-principles molecular dynamics simulations reveal that the depressur...

متن کاملPressure-induced Suppression of the Antiferromagnetic Transition in YbNi3Al9 Single Crystal
We have measured the electrical resistivity ρ(T ) of heavy fermion antiferromagnet YbNi3Al9 under hydrostatic pressure up to 8 GPa. We found that the antiferromagnetic ordering temperature TN is suppressed with increasing pressure, whereas the localized character of the trivalent Yb state becomes stronger inferred from the reduction of the Kondo scattering. We will discuss the possible origin o...
