On the anomalous CMN-He3 3 thermal boundary resistance

A. J. Leggett, M. Vuorio

Research output: Contribution to journalArticlepeer-review


It is proposed that the mechanism of the anomalously high thermal transfer rates observed between CAIN and liquid He3 is simply the electromagnetic dipole coupling between electrons and He3 nuclei. A crude theory based on this assumption explains the observed linear dependence of the Kapitza resistance RK on T, the order of magnitude of the coefficient, and the absence to date of the effect in dilute He3-He4 solutions. We predict that (1)RK(T) should go through a minimum at about 1 mdeg, (2)RK should be decreased by applying a magnetic field, (3) a similar linear T dependence (though with much larger coefficient) should be seen in dilute solutions below 5 mdeg, and (4) a similar, though probably less striking effect, should be observed for ferromagnetic metals in contact with He 3 at sufficiently low temperatures.
