Sažetak
We investigated the effects of magnetic field on a quasi-one-dimensional band of interacting electrons with a transverse dimerizing potential. One-particle problem in bond-antibond representation is solved exactly as well as the problem of magnetic breakdown through the dimerization gap. The resulting propagator is used to calculate the spin-density-wave (SDW) response of the interacting system within the matrix RPA for the SDW susceptibility. We find that the value of the anion potential fitting experiments in relaxed (TMTSF)_2ClO_4 is large, of the order of inter-chain hopping. In particular we predict the magnetic field induced transition of the first order between interband SDW0 and intraband SDW+/- phases. We reproduce the rapid oscillations with a period of 260 Tesla and the overall profile of the (TMTSF)_2ClO_4 phase diagram.
