# Title:Can a Magnetic Field Destroy a Spin-Density-Wave Phase in a Quasi-One-Dimensional Conductor?

Abstract: It is known that, in a pure one-dimensional case, Charge-Density-Wave (CDW) phase is destroyed by a magnetic field, whereas Spin-Density-Wave (SDW) one does not feel the field. In reality, 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 "anti-nesting" term in a Q1D electron spectrum, which destroys SDW phase. We suggest to perform the corresponding experiments in SDW phases of the real Q1D organic conductors with chemical formula (TMTSF)$_2$X (X=PF$_6$, ClO$_4$, etc.).
