Abstract

Results of recent superfluid fraction measurements of a 3He-4He mixture in aerogel are reported. It is observed that for the mixtures at low and intermediate 3He concentrations the critical behavior of the superfluid transition is not different from that of pure 4He in aerogel. Evidence of phase separation between 3He and 4He inside the aerogel is found at low temperatures. The phase separation region, however, is detached from the superfluid transition line, thus removing the tricritical point and creating a miscible superfluid mixture that is rich in 3He.
