A Comment on ``Superconducting-Normal Phase Transition in (Ba1-xKx)BiO3, x = 0.40, 0.47'' by B. F. Woodfield, D. A. Wright, R. A. Fisher, N. E. Phillips and H. Y. Tang, Phys. Rev. Lett. 83, 4622 (1999)
P. Kumar, Donavan Hall, R. G. Goodrich
This comment addresses criticisms of our PRL 82 (1999) p. 4532-4535 (cond-mat/9904288) raised by Woodfield et al. in their recent PRL. We find that the critical fields in single cr…

Collective Mode in a d_{x^2-y^2} + id_xy Superconductor
A. V. Balatsky, P. Kumar, J. R. Schrieffer
We consider a superconducting state with a mixed symmetry order parameter components, e.g. d+is or d+id' with d'= d_{xy}. We argue for the existence of the new orbital magnetizatio…
