Abstract: It is shown that the antiferromagnetic transition is preceded by the fermion condensation with rearrangement of single-particle degrees of freedom and appearance of plateaus in the spectrum of single-particle excitations. The results obtained are used to explain the gap structure in the spectrum of two-dimensional high-$T_c$ superconductors at $T=0$.
