Notes:
An extensive study of the low-field (μ0H ≤ 8 mT) dc initial susceptibility χin has been performed using micrometer-sized HTSC powders of varying sizes and methods of preparation. It is found, as before, that χin(T) is essentially constant for T (approximately-less-than) 0.4Tc. This supports s-wave pairing and implies no zeros of the gap on the fermi surface. Additionally, χin(T) finds reasonable description in a London model for superconducting spheres and a two-fluid model λ(T).
