| Abstract: | Magnetic susceptibility of three-dimensional Bose gas with ferromagnetic interaction was studied under external magnetic field within mean-field theory.The relationships of magnetic susceptibility with reduced temperature,with reduced ferromagnetic coupling constant,with lande factor,and with reduced magnetic field strength were discussed.Ferromagnetism under weak ferromagnetic interaction strength and paramagnetism was found to be conducive to the increase of magnetic susceptibility. |
