The peierls transition in per2[auxpt1−x(mnt)2]: pair-breaking field effects

Microwave experiments have been carried out on the two-chain organic compounds Per2[AuxPt1−x(mnt)2] (x=0;0.02; 1) as a function of temperature and magnetic field. A theoretical mean-field theory is proposed to show how pair-breaking effects due to either alloying, intrinsic disorder or localized spins modify the variation of the Peierls critical temperature of the Perylene stacks with the magnetic field.
