Confinement in Bechgaard salts: Anomalous magnetoresistance and nuclear relaxation

We present and analyze the normal phase temperature dependence of resistivity and nuclear spin-lattice relaxation of (TMTSF)2ClO4 under strong transverse magnetic fields. From a field-dependent scaling theory we show that the singular enhancement of the one-dimensional electron-electron umklapp scattering and antiferromagnetic spin correlations under field play a fundamental role in the large enhancement of magnetoresistance and nuclear relaxation of Bechgaard salts.
