Abstract
Solid molecular oxygen presents an interesting example of a low-temperature crystal which exists within several different magnetic phases. When solid solutions of argon and oxygen are formed with molar concentrations of oxygen between 60 and 80 %, a new structural and magnetic phase, known as the \(\delta \)-phase, appears at low temperatures. In order to investigate the nature of the \(\delta \)-phase, we carried out SQUID magnetometry measurements solid argon-oxygen solutions made up of 74 % oxygen and 26 % argon. In particular, we performed measurements of the magnetic susceptibility of the solid solutions over complete temperature cycles and isothermally as a function of time. Taken together, the experimental data demonstrate that that the \(\delta \)-phase is not an equilibrium thermodynamic state of the solid solutions, but is instead only a metastable state.
