Abstract
We show that in the Anderson model for a two-dimensional non-Fermi liquid a magnetic instability can lead to the itinerant electron ferromagnetism. Th e critical temperature and the susceptibility of the paramagnetic phase hav e been analytically calculated. The usual Fermi behavior is re-obtained by taking the anomalous exponent to be zero.
