Abstract
The observation of a small paramagnetic signal in a bulk s-wave superconductor Nb does not justify the conclusion drawn by Kostic et al. that our previous proposal interpreting the paramagnetism of ceramic high-Tc cuprates as arising from the d-wave symmetry of the superconducting state is unlikely to be correct. Several experimental tests are proposed to distinguish between paramagnetism caused by flux compression and that associated with unconventional symmetry.
