Anisotropy of an instability for a spin density wave induced by a magnetic field in a Q1D conductor
Lebed' A. G.
The threshold field for the formation of a spin density wave in (TMTSF)2X compounds is shown to have an oscillatory anisotropy in the plane perpendicular to the chains, Hla. This field is at a minimum for the direction making an angle φ ~ 30° with the c* axis.
