Destruction of the spin-density-wave phase by magnetic field in a quasi-one-dimensional conductor

It is known that, in a pure one-dimensional case, the charge-density-wave phase is destroyed by a magnetic field, whereas the spin-density-wave (SDW) phase does not "feel" the field. In reality, the SDW phase is often observed in quasi-one-dimensional (Q1D) conductors due to the so-called "nesting" property of their electron spectra. We show that, in the latter case, a high magnetic field generates some "antinesting" term in a Q1D electron spectrum, which destroys the SDW phase. We suggest performing the corresponding experiments in SDW phases of the real Q1D organic conductors with chemical formula (TMTSF)(2)X (X = PF6, ClO4, etc.).This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
