| Abstract: | Pauli paramagnetism of an weakly interacting Fermi gas is studied. The expression of susceptibility is derived analytically. Compared with ideal Fermi gas, the interaction of particles strengthen Pauli paramagnetism. Through the analysis of the fluctuation, it is shown that the strength of the external magnetic field should be higher than a critical magnetic field strength to appear the Pauli paramagnetism. |
