Osmotic pressure of 3He/4He mixtures at the crystallization pressure and at millikelvin temperatures
A. Salmela, A. Sebedash, J. Rysti, E. Pentti, J. TuoriniemiThe difference between the equilibrium concentration of He3 in the solid and liquid phases alters the crystallization pressure of helium mixtures due to osmotic pressure. This effect was determined with high precision at several concentrations from 0.6% to the zero temperature solubility limit of 8.1% by a specific capacitive pressure gauge. Thereby, the osmotic pressure was deduced at 2.53 MPa---the crystallization pressure of pure 4He---and at millikelvin temperatures. The experimental results are compared with numerical calculations for an interacting Fermi liquid using a quasiparticle potential and an effective mass fitted to experimental data.
