Abstract
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.
