Phase structure of Higgs-Yukawa systems with chirally invariant fermion actions (vol 50, pg 3387, 1994)

The behavior of the critical lines near the point of the appearance of the ferrimagnetic phase is revised within a mean-field approximation. We calculate the slopes of the lines at Such a point for the U(1) systems in the weak coupling regime. It is demonstrated that the slope of one of the critical lines is continuous, while a change in the slope of the other depends strongly on the number of the fermion flavors. We also find that in the ferrimagnetic phase near such a point the magnetization and the staggered magnetization align orthogonally to each other.
