Asymptotic expansions for the thermodynamic functions of an ideal spin-\textonehalf{} Fermi gas in a weak magnetic field are obtained about the point $z=1$ , where $z$ is the fugacity. We consider paramagnetism, diamagnetism, and paramagnetism plus diamagnetism together.

Asymptotic expansions for the thermodynamic functions of an ideal spin-\textonehalf{} Fermi gas in a weak magnetic field are obtained about the point

z=1

, where

z

is the fugacity. We consider paramagnetism, diamagnetism, and paramagnetism plus diamagnetism together. To relate to liquid

^{3}\mathrm{He}

films and bulk fluid, we study the spin paramagnetism in two and three dimensions.
