At constant temperature T, show that the vapour pressure p (T,B) of a paramagnetic liquid has the following dependence on the magnetic induction field B,

in the small field limit, i.e. cB0 RT². The liquid phase satisfies the Curie equation of state (9.106),where mℓ is the molar magnetisation. The molar volume vℓ of the liquid phase can be neglected compared to the molar volume vg of the gaseous phase, i.e. vℓ
