采用平均场理论研究外磁场中含铁磁耦合费米气体的热力学性质。引入朗德因子g衡量顺磁效应的强度，讨论了比热容和熵随约化磁场强度h、约化铁磁耦合强度?I、朗德因子g和约化温度t的变化关系，得到比热容与约化温度的1/2次方成正比的演化关系。

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.
