β¦ Synopsis
We suggest a universal theory of the field-induced spin-density-wave phase diagrams, experimentally observed in Γ°TMTSFΓ 2 X conductors. In particular, we show that, in layered quasi-one-dimensional conductors, the critical magnetic fields ratios, H 1 =H 0 ΒΌ 0:73; H 2 =H 0 ΒΌ 0:59, and H 3 =H 0 ΒΌ 0:49, are universal and do not depend on any fitting parameter. The suggested theory is in a good qualitative and quantitative agreement with the existing experimental data.

The field-induced SDW or CDW is shown to be characterized by a set of countably many order parameters (OP) of DW modulation due to interference between the lattice commensurability and magnetic length. The OP-distribution differs for every rational field, resulting in a phase diagram with devil's-st
