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 …

Magnetism in systems that do not contain transition metal or rare earth ions was recently
observed or predicted to exist in a wide variety of systems. We summarize both experimental …

By using a high-energy and high-brilliance synchrotron radiation source in the European
Synchrotron Radiation Facility and the Photon Factory, an angle-dispersive powder x-ray …

Molecular beam experiments are reported for collisions between oxygen molecules. Total
integral cross sections have been measured as a function of the collision energy with the …

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 …

The sloshing of liquids in low-gravity entails several technical challenges for spacecraft
designers and operators. Those include the generation of significant attitude disturbances …

Neutron-diffraction experiments were performed on polycrystalline samples of α− O 2 at 6
and 22 K and on β− O 2 at 30 K. A large amount of preferred orientation was observed in all …

The electrostatic and exchange interactions between two ground state 3~ g-O2 molecules
have been calculated ab initio by means of first order exchange perturbation theory. The …

The exchange interaction between Σ g 3− O 2 molecules, as obtained from ab initio
calculations for a singlet, triplet, and quintet dimer, can be well represented by the …

High field magnetization of solid oxygen is measured in the pulsed field up to 500 kOe. The
spin flop field H c in the antiferromagnetic α-phase is investigated in detail and exchange …
