Thermodynamic Properties of Polarized Liquid 3He along Different Isentropic Paths

The dependence of some thermodynamic properties of spin-polarized liquid 3He such as the velocity of sound, adiabatic index, isentropic compressibility and temperature on the spin polarization has been investigated along different isentropic paths. The Lennard- Jones potential has been used in our calculations. It has been found that for higher values of entropy, the spin polarization has greater effect on velocity of sound and adiabatic index with respect to those of lower entropies. Also for a certain value of entropy and density, the isentropic compressibility is almost insensitive to the variations in polarization.
