Abstract

We study the effect of quantum magnetic impurities on d -wave spin-density waves (d -SDW). The impurity spins are aligned coherently according to the spin space anisotropy of the condensate. Both the order parameter and transition temperature increase due to the coherent interplay between magnetic scatterers and d -SDW. This can explain the recent experimental data on the pseudogap enhancement of Ni substituted Nd Ba2 (Cu1-y Niy) 3 O6.8 from A. V. Pimenov [Phys. Rev. Lett. 94, 227003 (2005).].
