British Association Discussions: Low Temperature Physics

Abstract

FOR many years, interest in low temperature physics was largely confined to the phenomenon of superconductivity. During the past four years, however, new phenomena have received attention, and at the session of Section A (Physics) on August 22 devoted to low temperature physics, comparatively little time was devoted to superconductivity. Attention was concentrated instead upon the Debye-Giauque effect, that is, the cooling of certain paramagnetic substances by adiabatic demagnetization, and upon the curious phenomenon of liquid helium II.
