✦ Synopsis

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-staircase-like infinite cascades. Recent experiments on (TMTSF)2X are investigated.
