摘要：
A spin-fluctuation theory of quasi-two-dimensional itinerant-electron ferromagnets is developed. On the basis of an anisotropic spin-fluctuation spectrum, interpolating between two-dimensional (2D) and three-dimensional (3D) cases, we discuss the possibility Of observing two-dimensional critical behaviours as well as the crossover phenomena between the 2D and 3D limits.
