Query: An Alternative Interpretation of the Magnetic Penetration Depth Data on
  Pr(2-x)Ce(x)CuO(4-y) and La(2-x)Ce(x)CuO(4-y)   We have revisited the magnetic penetration depth data on the electron-doped
cuprates Pr(2-x)Ce(x)CuO(4-y) and La(2-x)Ce(x)CuO(4-y). It is proposed that the
transition between the nodal-gap-like and nodeless-gap-like behaviors upon
electron-doping [see, e.g., M. Kim et al., Phys. Rev. Lett. 91, 87001 (2003)]
can be due to a scattering of the quasiparticles in the d-wave superconducting
state by an incipient or weak antiferromagnetic spin-density-wave. This
conjecture is supported by the inelastic neutron scattering and angle-resolved
photoemission experiments on some closely related electron-doped cuprates.
