We consider the ground state magnetic phase diagram of the two-dimensionalHubbard model with nearest and next-nearest neighbor hopping in terms ofelectronic density and interaction. We treat commensurate ferro- andantiferromagnetic, as well as incommensurate (spiral) magnetic phases. Thefirst-order magnetic transitions with changing chemical potential, resulting ina phase separation (PS) in terms of density, are found between ferromagnetic,antiferromagnetic and spiral magnetic phases. We argue that the account of PShas a dramatic influence on the phase diagram in the vicinity of half-filling.The results imply possible interpretation of the unusual behavior of magneticproperties of one-layer cuprates in terms of PS between collinear and spiralmagnetic phases. The relation of the results obtained to the magneticproperties of ruthenates is also discussed.
