英文摘要	We consider a model of an Anderson impurity embedded in a d(x2-y2)-wave superconducting state to describe the low-energy excitations of cuprate superconductors doped with a small amount of magnetic impurities. Because of the Dirac-like energy dispersion a sharp localized resonance above the Fermi energy, showing a marginal Fermi liquid behavior (omega ln omega as omega --> 0), is predicted for the impurity states. The same logarithmic dependence of self-energy and a linear frequency dependence of the relaxation rate are also derived for the conduction electrons, characterizing a new universality class for the strong coupling fixed point. At the resonant energies, the spatial distribution of the electron density of states around the magnetic impurity is also calculated. DOI: 10.1103/PhysRevLett.86.704.
