A symmetry analysis has yield the slightly noncollinear antiferromagnetic structure of La2Cu04 (Z> Ц). A first-order transition can occur to a slightly ferromagnetic phase in a magnetic field. This transition is accompanied by a change in the initial antiferromagnetic structure. The results are compared with experimental data (R. J. Birgeneau etal.t Preprint, 1988; T. Thio etal.f Preprint, 1988).
