TL;DR: In this article, the authors measured the temperature change at the magnetic-field-induced alpha-theta phase transition of solid oxygen and found that the significant temperature increase from 13 to 37 K, amounting to 700 J/mol, is due to the irreversible heating at the first order phase transition.

TL;DR: In this paper, the authors observed three-dimensional long-range ordering of Haldane-gap antiferromagnet NDMAZ at around T ⋍ 0.3 K above H ⋈ 13 T (H | c ), which is ascribed to both the field-induced gap quenching and the existence of finite interchain interaction.

TL;DR: In this paper, high-field magnetization measurements have been performed at various temperatures on the molecular oxygen adsorbed in a microporous coordination polymer CPL-1, and the magnetic properties can be explained by not the S = 1 Heisenberg antiferromagnetic dimer model but the O2-O2 dimers model taking into account the spin-dependent intermolecular potential.

TL;DR: In this article, a Haldane system was studied in the magnetic field up to 10 T in order to investigate the field-induced long-range ordering and the spin excitation.

TL;DR: Katsumata et al. as mentioned in this paper showed that the volume magnetostriction in the oxygen phase exhibits no greater than $2/ifmmode/times\else\texttimes\fi{{10}^{\ensuremath{-}3}$ at 5 T.
