Umklapp processes in two-fold commensurate compounds (TMTSF)2X result in the coexistence of two spin density waves in the magnetic field. One of them corresponds to the vector of ideal nesting and causes known phase transitions. The other wave corresponds to the vector of direct nesting and causes fast oscillation of the physical values.
