In a superfluid liquid-helium cavity packed with a fine powder, only the supercomponent is free to move and pressure waves transmitted by the supercomponent are called “fourth sound.” We have observed that the resonance frequency of the powder-filled chamber may be shifted by introducing...
Measurements of the melting curve of He3 have been made between 16.6° mK and 0.7°K. The liquid and solid molar volumes at melting have been extended from 0.33°K to below 0.03°K, and the molar volume change on melting ΔV
obtained. An increase in ΔV
from 1.20 cm3/mole at 0.33°K to 1.28...
We have investigated the temperature dependence of the upper critical fieldH
and the thermodynamical fieldH
for superconducting Mo-Re alloys containing magnetic impurities. In addition, the temperature dependence of the Ginzburg-Landau parameters κ1(T) and κ2(T) has been determined by...
We present the results of a series of experiments on the mobility of negative ions trapped on quantized vortex lines in superfluid helium. Trapped-ion mobilities were measured as a function of temperature, pressure, and He3 concentration. Some of the experimental data have been previously...
The conventional theory of nonideal solutions is modified on the basis of Gorter's hypothesis, and various properties of He3 and He4 solutions are investigated. The variation of λ-temperature with He3 concentration is explained adequately right up to the phase separation region. A comparison...
A detailed analysis of the electromagnetic attenuation in superconductors has been carried out, with specific reference to type I materials. The rapid rise atT
predicted by Cullen and Ferrell is found to be most pronounced in superconductors with low acoustic velocities. Also, the effect...
It is shown that the results of the Pellam Rayleigh disk experiment are accounted for by the thermohydrodynamic equations when the relative velocity between the normal and superfluid components is included and the probe acts as an isothermal boundary.
Using a method due to Bloch, it is shown that in thermodynamic equilibrium an annular container of mean radiusR, massM, containingN atoms of helium II of massm each will, when subjected to a torque τ, evince oscillations in its angular acceleration about the classical value. The frequency, ν, of...
