利用自洽重整化（SCR）自旋涨落理论讨论了二维流动电子系统中的铁磁自旋涨落。在有限温度下不存在长程磁序。处理静态和动态磁化率的温度依赖性以及与自旋涨落相关的物理性质，例如比热、核自旋晶格弛豫率和电阻率，特别关注磁不稳定性周围的关键行为。
Ferromagnetic spin fluctuations in two-dimensional itinerant electron systems are discussed by using the self-consistent renormalization (SCR) theory of spin fluctuations. There is no long range magnetic order at finite temperatures. The temperature dependences of the static and dynamical susceptibilities and the physical properties associated with the spin fluctuations such as specific heat, nuclear spin-lattice relaxation rate and electrical resistivity are treated with particular attention to the critical behaviors around the magnetic instability.
