Abstract

Historically the study of the boundary resistance between the paramagnetic salt cerium magnesium nitrate (CMN) and liquid 3He has been important because of its influence on thinking about thermal coupling at very low temperatures. Bishop et al.[1] and Black et al.[2] used a spin-relaxation technique to determine the total thermal resistance between the Ce spins and 3He. For single crystals they found R \( \underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{ \propto } \) 1/T2 which they attributed to an internal resistance within the sample. In contrast, with powdered specimens, the total resistance actually fell for T < 20 mk and from these data the influential idea of a direct magnetic coupling between the ions and the 3He nuclei was born and was later developed by Leggett and Vuorio [3]. The idea has been criticised strongly in a review paper by Harrison [4].
