测量了各向同性铁磁体Ni_2MnGa的磁化强度与磁场的关系，居里温度接近363.0（0.4）K，临界折射率δ为4.77（0.50）。分析了该指数与纯镍的指数是否可用Takahashi的弱铁磁巡游电子系统理论或传统的分子场理论来描述。(c)2007 Elsevier B.V.保留所有权利。
The field dependence of the magnetization of the isotropic ferromagnet, Ni2MnGa has been measured close to the Curie temperature of 363.0 (0.4) K and the critical index delta has been determined to be 4.77 (0.50). An analysis has been carried out to see if the index together with that of pure nickel could be described by the theory by Takahashi for a weakly ferromagnetic itinerant electron system or by conventional molecular field theory.
