英文摘要：

Thermodynamic properties of Fermi gas with ferromagnetic coupling were studied under external magnetic field within mean-field theory.The strength of paramagnetic effect was measured by the Lande-factor.Specific heat and entropy with reduced magnetic field strength, reduced ferromagnetic couplings intensity,Lande-factor and reduced temperature were calculated.Data showed that the specific heat was proportional to the square of reduced temperature.
