Abstract
We have studied the transverse magnetoresistance of the organic series (DMtTSF)2 X down to 2 K and up to 40 T. Under about 20 K and 8 T a negative magnetoresistance appears only for salts whose X is a tetrahedral anion. This new phenomenon is interpreted as a two-dimensional (2D) weak localization effect.
