“Researches on the magnetization of liquid and solid oxygen”

Abstract

It is scarcely necessary to remark that the investigation of the magnetic properties of oxygen at low temperatures has long occupied a position on the programme of the cryogenic laboratory, or that this has been considered one of the most important items on the programme since the investigation of both liquid and solid oxygen has been made possible by the perfecting of the methods ¹) of obtaining detailed series of measurements at constant temperatures in the region of liquid hydrogen. Indeed, while the strongly magnetic properties of oxygen of themselves select it from all other substances as especially suitable for the study of para-magnetism, we can in the meantime for no other substance obtain the magnetic equation of state ²), which gives a representation of the magnetic properties of a substance in the three states of aggregation at as many successive temperatures and pressures as possible.
