Revised thermodynamic relations for lambda transitions in mixtures. II. Special relations for Curie points and Neel points

For pt. I see ibid., vol.5, 1004 (1972). On the basis of the behaviour of magnetic and electric susceptibilities, and of magnetostriction and electrostriction, the possibility is investigated of obtaining additional Pippard relations for the effect of change of composition on (magnetic or electric) Curie points and Neel points of mixtures. The question is aired of whether further such relations might not sometimes be obtainable on the basis of the behaviour of properties other than equilibrium thermodynamic properties.
