17O and 63Cu NMR of electron-doped High-Temperature Superconductor Pr1.85Ce0.15CuO4 — •Michael Jurkutat1, Grant Williams2, Damian Rybicki1, and Jürgen Haase11Universität Leipzig, Fakultät für Physik und Geowissenschaften, Postfach 100920, 04009 Leipzig, Germany — 2The MacDiarmid Institute, Industrial Research, P.O.Box 31310, Lower Hutt 5040, New Zealand

We present results of a nuclear magnetic resonance (NMR) study of c-axis aligned powder samples of the electron-doped high temperature superconducting cuprate Pr1.85Ce0.15CuO4. In particular the effect of partial Ni substitution for Cu on 63Cu NMR is investigated as a function of temperature, crystal orientation and Ni substitution. We find Ni-induced broadening of the spectra and temperature-dependent effects on spin-lattice relaxation indicating spin density oscillations about the Ni site. Furthermore we analyse the temperature and field dependence of 17O NMR spectra showing unexpected resemblances to hole-doped systems.
