Magnetic structure of beta-oxygen
Abstract
Possible types of magnetic ordering in the beta-phase of solid oxygen are studied using the symmetry approach. It is shown that the orientationally disordered magnetic structure with the alternating type of polarizations in neighboring antiferromagnetic X-Y planes is the most probable structure in this crystal. The unipolar model of antiferromagnetic structure of beta-oxygen proposed so far is found to be unstable against exchange-striction monoclinic distortions of the crystal lattice and contradicts X-ray diffraction data.
