Magnon-assisted dynamics of a hole doped in a cuprate superconductor

Commensurate spin dynamics in the superconducting state of an electron-doped cuprate superconductor.

We report neutron scattering studies on two single crystal samples of the electron-doped (n-type) superconducting (SC) cuprate Nd2-xCexCuO4 (x=0.15) with T(c)=18 and 25 K. Unlike the hole-doped (p-type) SC cuprates, where incommensurate magnetic fluctuations commonly exist, the n-type cuprate shows commensurate magnetic fluctuations at the tetragonal (1/2 1/2 0) reciprocal points both in the SC...

A photoemission investigation of the superconducting gap in an electron-doped cuprate superconductor

We have performed angle resolved photoelectron spectroscopy (ARPES) on the electron-doped cuprate superconductor Nd Ce CuO . Evidence is found for an anisotropic superconducting gap that is consistent with the existence of a 1.85 0.15 4 d-wave superconducting order parameter in the n-type cuprate superconductors.  2001 Elsevier Science B.V.
