| Research Abstract |
Solid oxygen is the only simple homonuclear diatomic molecule having a magnetic degree of freedom, and shows various magnetisms and crystal structures as a function of temperature and pressure. Although there are several suggestions of pressure-temperature phase diagram through mainly optical experiments, the diagram is still controversial. In this research project, we have tried to determine the phase boundary of solid oxygen thermodynamically. We have established the diagram of solid oxygen up to 5 GPa and below room temperature via thermodynamic quantities, such as specific heat and magnetic susceptibility under pressures, developed in this project, and discovered a possible new solid phase.
