Abstract
A typical sample that can be accommodated in a high-pressure diamond-anvil cell is about 300 μm in diam and 100 μm thick. In this microscopic working volume we observed phase transitions of various condensed gases. Pressures were determined from measurements of fluorescence line shift in a ruby chip imbedded in the sample. We observed freezing in the gases and we conclude that solid phase transitions can be detected by the sudden changes they cause in depolarization of transmitted light, even when viewed through stressed diamond anvils.
