Solid oxygen

YA Freiman, HJ Jodl - Physics Reports, 2004 - Elsevier
Solid oxygen is a unique crystal combining properties of a simple molecular solid and of a
magnet. Unlike ordinary magnets, the exchange interaction in solid oxygen acts on a …

Cluster Structure of the Epsilon Phase of Solid Oxygen

H Fujihisa, Y Akahama, H Kawamura, Y Ohishi… - Physical review …, 2006 - APS
Despite many experimental and theoretical studies, the crystal structure of the ε phase of
solid oxygen has not been determined. We performed powder x-ray diffraction experiments …

Evidence for a magnetic collapse in the epsilon phase of solid oxygen

IN Goncharenko - Physical review letters, 2005 - APS
Solid oxygen is the only elementary molecular magnet. Under the very high pressure of 96
GPa oxygen transforms into a metal and a superconductor. Theory predicts a nonmagnetic …

Low-Energy Linear Structures in Dense Oxygen: Implications for the Phase

JB Neaton, NW Ashcroft - Physical review letters, 2002 - APS
Using density functional theory implemented within the generalized gradient approximation,
a new nonmagnetic insulating ground state of solid oxygen is proposed and found to be …

Helical Organic and Inorganic Polymers

S Hirata, Y Shigeta, SS Xantheas… - The Journal of Physical …, 2023 - ACS Publications
Despite being a staple of synthetic plastics and biomolecules, helical polymers are scarcely
studied with Gaussian-basis-set ab initio electron-correlated methods on an equal footing …

High pressure structural changes in amorphous polymeric carbon monoxide by combined infrared spectroscopy and X-ray diffraction

M Santoro, R Bini, M Ceppatelli… - The Journal of …, 2022 - ACS Publications
The high pressure transformation of carbon monoxide into an amorphous polymeric material
(a-pCO) is known since decades, yet the determination of its local structure is made difficult …

Molecular character of the metallic high-pressure phase of oxygen

AF Goncharov, E Gregoryanz, RJ Hemley, H Mao - Physical Review B, 2003 - APS
We report Raman measurements of solid oxygen under high static pressures up to 134 GPa
through the transition to the metallic phase. Contrary to previous studies, we observed a …

Noncollinear magnetism in liquid oxygen: A first-principles molecular dynamics study

T Oda, A Pasquarello - Physical Review B—Condensed Matter and Materials …, 2004 - APS
