Abstract

The effects of varying the hole concentration and the concentration of nonmagnetic (Zn) impurities on the spin excitation spectra of YBa2Cu3O6+x are compared and contrasted. With decreasing hole concentration, the magnetic resonance peak observed below Tc for x = 1 is shifted to lower energies, but remains sharp and continues to set in at Tc. By contrast, a minute concentration (0.5%) of nonmagnetic impurities broadens the spectrum dramatically. The broadened spectral distribution persists up to temperatures significantly higher than Tc.
